Description

LCD Digital Heating Magnetic Stirrer (MS‑H280‑F500)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Modular, Medium‑Capacity Heating for Clinical and Pharmaceutical Preparations
Primary Use: Provides a programmable LCD digital heating magnetic stirrer with a dedicated 500 mL round‑bottom flask heating mantle, fitted with a high‑quality alumina silica fiber sleeve (inner diameter 118.75 mm). Designed for the controlled, uniform heating and simultaneous stirring of medium‑to‑large volume patient samples, reagents, and biological specimens in clinical diagnostics, pharmaceutical research, and academic laboratories. The system features a maximum stirring capacity of 20 L (water) on its Ø135 mm ceramic‑coated aluminium work plate (when the mantle is detached), a speed range of 200‑1500 rpm (±20 rpm), and a heating temperature range of 25 °C to 280 °C in 1 °C increments. The high‑resolution LCD digital display simultaneously shows set and actual values for temperature, stirring speed, and timer status.

How it helps: For the clinical chemist and pharmaceutical research scientist, the precisely contoured 500 mL round‑bottom flask heating mantle (inner diameter 118.75 mm) ensures maximum surface‑to‑flask contact, eliminating localised hot spots that could degrade heat‑sensitive clinical reagents. The intelligent interchangeable heating sleeve design allows flexible configuration with 100 mL, 250 mL, 500 mL, and 1000 mL round‑bottom flasks, as well as flat‑bottom beakers, which can be interchanged arbitrarily. The unit can also be run as two independent devices – one heating (using the mantle) and one stirring (using the work plate) – simultaneously, dramatically improving instrument utilisation in lean diagnostic laboratories. For the patient receiving cell‑based therapies or pharmaceutical formulations, the reproducibility and thermal uniformity of the platform ensure consistent conditions for critical diagnostic sample preparation, supporting accurate test results and the safe development of new compounds.

2. Medium‑Volume Trace Element Digestion and Clinical Sample Preparation
Primary Use: Used for the controlled digestion of up to 500 mL of patient serum, whole blood, urine, and tissue homogenates in strong acids at temperatures up to 280 °C, prior to trace element analysis by atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP‑MS). The built‑in temperature self‑calibration function and PT1000 external temperature sensor port (±0.2 °C accuracy) enable precise closed‑loop control of the actual sample temperature.

How it helps: For the trace element analyst processing medium‑volume patient samples in toxicology and occupational health screening, the 500 mL capacity supports the simultaneous digestion of a full batch of blood lead, urine cadmium, or heavy metal panel specimens in a single run, significantly reducing total preparation time. The PT1000 external temperature sensor enables the instrument to regulate the actual temperature of the acid digest directly, ensuring complete, uniform oxidation of organic matrices even in demanding applications. The integrated temperature self‑calibration function (customer‑accessible) and dual independent safety circuits continuously monitor system status; if a sensor failure, over‑temperature (>420 °C), or short circuit is detected, the device stops heating, displays an error code, and cuts off power. For the patient undergoing heavy metal screening or nutritional deficiency monitoring, the accurate, controlled digestion achieved results in precise and reliable clinical measurements, free from matrix interference, directly supporting correct diagnosis and treatment.

3. Benchtop Gel Melting, Bulk Culture Media Preparation and Clinical Quality Control
Primary Use: Enables safe, uniform heating and melting of solid or semi‑solid culture media, nutrient agars, and agarose gels directly in 500 mL round‑bottom flasks, and the preparation of temperature‑sensitive standard solutions and buffers for high‑throughput molecular diagnostics and clinical microbiology workflows. The heating mantle securely holds the vessel, allowing the top half to remain visible for easy monitoring of liquid level, clarity, and dissolved solids during operation.

How it helps: For the clinical molecular biologist and microbiology technologist processing large numbers of patient samples, the 500 mL mantle capacity supports the preparation of up to 100‑125 culture plates or 40‑50 standard electrophoresis gels in a single batch without the need for oversized equipment. The glass‑fibre inner sleeve with high‑quality aluminium‑silicate wool provides superior heat retention and 500 °C thermal resistance, allowing solid media to melt evenly without localised scorching that could degrade nutrients. The high‑performance alumina silica fiber sleeve ensures precise temperature control, uniform heating, and corrosion resistance, guaranteeing that solid residues such as nutrient powders are completely dissolved. The integrated programmable timer enables fully unattended, automated operation for quality control applications. For the patient, correctly prepared, homogeneous media in sufficient batch volume ensures that bacterial identification and molecular diagnostic testing for infectious diseases are accurate, timely, and reproducible across large numbers of patient specimens.

4. Dual‑Mode Versatility for Pharmaceutical Quality Control and Industrial‑Scale R&D
Primary Use: The instrument can be used in three independent configurations: as a complete heating and stirring unit (when the mantle is attached), as a stirring‑only unit on its 20‑litre capacity ceramic‑coated work plate (when the mantle is detached), or as a dual‑purpose system where one unit heats (using the mantle) while a separate, independent unit stirs (using the work plate) simultaneously.

How it helps: For the laboratory manager and R&D director, the ability to run a 500 mL synthesis on the heating mantle while simultaneously stirring a 5‑litre beaker of buffer on the work plate dramatically improves productivity. A single 3.7 kg instrument can process a significant batch of patient digests or QC standards, then be reconfigured for general stirring tasks between runs – reducing equipment duplication and saving valuable laboratory bench space. The intelligent modular design enables a single instrument to accomplish the work of two separate pieces of equipment, lowering overall acquisition and maintenance costs. For the patient, streamlined, standardised processing of QC materials means fewer procedural errors across moderate‑volume sample runs, supporting faster, more accurate diagnostic test results.

SECONDARY & SUPPORTIVE USES

1. Medium‑scale chemical synthesis and reflux for pharmaceutical research: Provides stable, uniform heating for distillation, reflux, and digestion of organic compounds in 500 mL round‑bottom flasks, supporting fine chemical, pharmaceutical, and industrial research – with the ability to reach 280 °C for refluxing high‑boiling‑point solvents. The instrument is suitable for scientific research, industrial and mining applications, food processing, biochemistry, agriculture, petrochemistry, and pharmaceutical industries.

2. Bulk solvent evaporation and concentration for analytical chemistry: Gently heats organic solvents in 500 mL round‑bottom flasks to remove volatile components and concentrate non‑volatile analytes; the PT1000 external temperature sensor provides ±0.2 °C accuracy for controlled evaporation rates in environmental analysis, food safety testing, and pharmaceutical formulation development – ideal for processing multiple extracts where smaller evaporators would be inefficient.

3. Dissolution testing for large‑scale drug development: Provides precise heating to simulate dissolution and stability test conditions for solid oral dosage forms (tablets, capsules) placed in a 500 mL beaker or round‑bottom flask containing heated buffer solutions. The 500 mL capacity is optimal for QC‑level dissolution testing, as it can accommodate a standard dissolution vessel with complete agitation.

4. Protein denaturation and enzyme inactivation for industrial biochemistry: Heats protein solutions in a 500 mL flask to temperatures above 70 °C to completely denature enzymes and coagulate proteins, stopping enzymatic reactions before downstream analysis in protein purification and enzyme assay workflows – providing full denaturation for industrial‑scale biochemistry applications.

5. Education and advanced teaching laboratory heating for chemistry demonstrations: Serves as a versatile, user‑friendly teaching tool for demonstrating the principles of distillation, reflux, solution preparation, and chemical reaction kinetics in university chemistry, clinical laboratory science, and pharmaceutical laboratory courses. The compact 3.7 kg benchtop design with high‑visibility LCD screen and incremental digital controls is ideal for student‑accessible workstations.

6. Geochemical, mining and environmental large‑batch sample preparation: Prepares solid environmental and mining samples – such as soils, sediments, rocks, and ores – by acid‑digesting or ashing them in preparation for analysis of mineral content and elemental pollutants. The high‑temperature‑capable mantle (280 °C) can handle heavy crucibles and aggressive acids, with 500 mL capacity enabling processing of representative bulk samples with high throughput.

3. PHYSICAL & OPERATIONAL PROPERTIES

Construction: Durable, fire‑resistant metal outer casing with an interchangeable heating mantle. The heating mantle is constructed from a high‑quality aluminium‑silicate (ceramic) wool inner liner (alumina silica fibre sleeve), which provides excellent thermal insulation, uniform heating, and corrosion resistance. The aluminium‑structure mantle has a powder‑coated, corrosion‑resistant outer shell for efficient heat transfer and a long service life.
Heating mantle (F500 variant): Dedicated 500 mL round‑bottom flask heating mantle with an inner diameter of 118.75 mm, precisely contoured to maximise surface‑to‑vessel heat transfer and ensure uniform thermal contact. The alumina‑fibre sleeve allows the top half of the flask to remain visible for easy monitoring of liquid level, clarity, and dissolved solids during operation.
Flexible interchangeable heating sleeves: The driving unit can be flexibly configured with interchangeable heating jackets for 100 mL, 250 mL, 500 mL and 1000 mL round‑bottom flasks (F series) and flat‑bottom beakers (B series), which can be interchanged arbitrarily. This modular design allows the same base unit to be reconfigured for a wide range of vessel sizes without purchasing a separate instrument.
Dual‑mode operation (“Two‑in‑One” mode): The instrument can be used in three independent configurations:
- Mode 1 (Heating + Stirring on Mantle): The mantle provides simultaneous heating and stirring of the contents of the 500 mL round‑bottom flask.
- Mode 2 (Stirring‑Only): The mantle can be detached, and the instrument functions as a standard 20‑litre magnetic stirrer on its φ135 mm ceramic‑coated work plate.
- Mode 3 (Dual‑purpose Operation – Heat + Stir independently): One unit heats (using the heating mantle) while a separate, independent unit stirs (using the 20‑litre capacity work plate). This offers genuine two‑device‑in‑one capability, dramatically improving laboratory productivity.
Display: High‑contrast LCD digital display simultaneously shows set and actual values for temperature and speed, as well as timer status, providing complete operational visibility without toggling options.
Operation: Simple, intuitive digital controls with tactile buttons for temperature, speed and timer programming. Incremental 1 °C temperature adjustment and 1 rpm speed resolution allow precise setting of experimental parameters.
Heating technology: PID‑controlled heating with an advanced microprocessor for stable, overshoot‑free temperature regulation, with or without the external PT1000 sensor. The built‑in temperature self‑calibration function (customer‑accessible) allows the user to correct for minor temperature offsets, ensuring exceptional measurement accuracy over time.
Stirring system: Powerful rare‑earth magnets provide strong magnetic coupling, preventing stir bar decoupling even with viscous liquids or at high speeds. The brushless DC motor provides stable torque and ultra‑quiet, vibration‑free operation.
Safety functions:
- Dual independent safety circuits: Two independent safety circuits continuously monitor system status; a PT1000 alert occurs in case of sensor failure; if sensor failure or over‑temperature is detected, the machine reports an error and stops heating; if the first safety circuit fails and a short circuit occurs, the second safety circuit cuts off the power supply to ensure operator safety.
- Residual heat warning (“HOT” indicator): The “HOT” safety indicator activates when the heating mantle exceeds 50 °C and continues flashing on the display even after the unit is turned off (including unplugged). This critical safety feature alerts users to the dangerously hot surface until the plate/mantle is safe to touch (temperature drops below 50 °C).
- 420 °C over‑temperature protection (hardware cutoff): A separate thermal cut‑off sensor shuts down heating if the work plate exceeds 420 °C, preventing runaway heating, fire hazards, and sample destruction even if the primary control system fails.
Spill protection: IP21‑rated metal housing offers protection against solid foreign objects >12.5 mm and vertically falling water drops. The fire‑resistant metal housing also provides protection against chemical spills and is easy to clean.
Portability: Compact benchtop design with a small footprint of 295 × 160 mm and light weight (3.7 kg), easily moved between workstations.
Maintenance: The brushless DC motor is maintenance‑free, requiring no routine brush replacement or lubrication. The ceramic‑coated work plate and metal housing are easy to clean with a mild detergent and soft, damp cloth.
Included accessories: The package includes the PT1000 external temperature sensor, support rod, support clamp and magnetic stirring bar.

4. STORAGE & HANDLING ATTRIBUTES

Storage: Store the instrument in a clean, dry, dust‑free environment at room temperature (15‑30 °C) when not in use. Allow the unit to cool completely (verify “HOT” indicator is off) before storage. The heating mantle should be stored in a dry, clean environment to prevent moisture ingress into the fibre insulation.
Installation: Place the instrument on a stable, level, non‑flammable, heat‑resistant laboratory benchtop away from flammable materials, volatile solvents, combustible gases, or paper products. Allow at least 10 cm clearance on all sides for heat dissipation. Do not use near water baths or sinks where splashing may occur.
Cleaning: Unplug the unit and allow it to cool completely before cleaning. Wipe the ceramic‑coated work plate, the fire‑resistant metal housing, and the outer surface of the heating mantle with a soft, damp cloth using a mild laboratory detergent or 70 % isopropyl alcohol. For stubborn residues inside the heating mantle, use a non‑abrasive cleaner suitable for glass‑fibre surfaces. Do not immerse the unit in liquid. Do not use abrasive cleaners or metal‑scouring pads. Do not saturate the fibre insulation inside the heating mantle with liquid.
Pre‑use inspection: Before each use, inspect the power cord and plug for any damage. Ensure the heating mantle is free of cracks and foreign objects. Verify that the correct heating mantle size (500 mL) is fitted for the round‑bottom flask being used. Check that the flask is dry, free of cracks, and properly seated in the mantle for maximum surface contact.
Round‑bottom flask selection for heating mantle: Use only standard 500 mL round‑bottom flasks made of borosilicate glass (e.g., Pyrex or Kimax) designed to withstand the operating temperature up to 280 °C. Do not use cracked or damaged glassware. The inner diameter of the 500 mL round‑bottom flask mantle (118.75 mm) is specifically designed for a snug, secure fit.
Operation with external sensor (PT1000): Insert the PT1000 temperature sensor probe into the sample vessel and secure it with the support clamp. Do not allow the sensor wire to contact the hot heating mantle, as this may melt the insulation and cause sensor failure or an electrical hazard.
Attaching and removing heating mantles: Ensure the driving unit is turned off and cool. The interchangeable mantle attaches via a dedicated connector. To remove after use, allow the mantle to cool completely (“HOT” indicator off) before disconnecting.
Independent dual‑purpose operation (“two‑in‑one mode”): To run the instrument as two separate devices (one heating on the mantle, one stirring on the base work plate), follow the manufacturer’s configuration instructions in the user manual.
Temperature self‑calibration: To perform a self‑calibration, follow the manufacturer’s procedure using a calibrated external thermometer.
Timer operation: Program the timer for the desired heating and stirring duration. When the timer reaches zero, the unit stops heating but continues stirring (if stirring was enabled), and the buzzer sounds. Press any button to silence the buzzer.
Cooling down: After use, turn off the power and allow the heating mantle to cool completely until the “HOT” indicator stops flashing (typically 30‑60 minutes, depending on operating temperature) before cleaning, moving, storing, or changing the mantle.
Periodic verification: Verify temperature accuracy periodically using a calibrated external thermometer. If deviation exceeds specifications (±1 °C <100 °C or ±1 % >100 °C), perform a temperature self‑calibration routine.

5. LABORATORY & CLINICAL APPLICATIONS

Primary Application: General‑purpose, medium‑to‑large‑volume heating and stirring for clinical diagnostics (trace element digestion for heavy metal testing – blood lead, urine cadmium, heavy metals), pharmaceutical quality control, analytical chemistry (reflux, distillation, solvent evaporation), mining and geochemistry sample preparation, and academic research laboratories where the ability to heat round‑bottom flasks and flat‑bottom beakers on a single versatile platform is required.
Clinical Role: A versatile and essential benchtop instrument for hospital and clinical chemistry laboratories, toxicology departments (blood lead, urine cadmium, heavy metals), pharmaceutical R&D and quality control, analytical chemistry departments, environmental testing stations, mining laboratories, and research institutions. Critical for medium‑batch sample digestion for trace element analysis, agarose gel preparation (40‑50 gels per batch), clean and efficient culture media preparation (100‑125 plates per batch), and reliable dissolution testing where precise, safe, and versatile heating with stirring is mandatory for diagnostic accuracy and patient safety.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Burn Hazard — High Plate and Mantle Temperature: The work plate can reach 280 °C, and the heating mantle remains dangerously hot for an extended period after the power is turned off. Do not touch the work plate or heating mantle for at least 30‑60 minutes after use, or until the residual heat “HOT” indicator stops flashing. Use appropriate heat‑resistant gloves or tools when handling vessels on the hot plate. Severe burns can occur upon contact.
Residual Heat Warning — Continues Even When Off: The “HOT” safety indicator activates when the work plate exceeds 50 °C and continues flashing on the display even after the unit is turned off (if still connected to mains). This critical safety feature alerts users to the dangerously hot surface until the plate is safe to touch (temperature drops below 50 °C). Always verify that the “HOT” indicator has stopped flashing before touching the plate or mantle.
Fire Hazard — Avoid Flammable Materials: Do not operate the instrument near flammable materials, volatile solvents, combustible gases, or paper products. Keep the work area clear of flammable substances. The heating temperature must be set at least 50 °C lower than the ignition point of the chemicals being used. Do not leave the instrument unattended while operating at high temperatures without appropriate safety protocols. The independent safety circuit (420 °C cutoff) provides backup protection but should not replace operator vigilance.
Over‑Temperature Protection — Dual Independent Safety Circuits: The instrument has dual independent safety circuits that continuously monitor the device. If the work plate exceeds 420 °C or a built‑in sensor malfunctions, the machine stops heating, displays an error message and may sound an audible alarm. If the first safety circuit fails and a short‑circuit is detected, the second safety circuit cuts off the power supply to ensure operator safety.
Interchangeable Heating Mantle — Correct Attachment and Removal: Ensure the driving unit is turned off and cool before attaching or removing heating mantles. The interchangeable mantle attaches via a dedicated connector. Fit the mantle firmly onto the work plate and lock it according to the manufacturer’s instructions. To remove after use, allow the mantle to cool completely (verify “HOT” indicator is off) before disconnecting. Only use mantles specifically designed for this model.
Vessel Selection — Proper Flask Fit: Use only standard 500 mL round‑bottom flasks made of borosilicate glass (e.g., Pyrex or Kimax) designed to withstand the operating temperature up to 280 °C. Do not use cracked, damaged, or non‑borosilicate glassware. The inner diameter of the 500 mL round‑bottom flask mantle (118.75 mm) is specifically designed for a snug, secure fit. A loose‑fitting flask can cause uneven heating and create a fire hazard.
Thermal Shock — Gradual Heating Only: Do not place a cold flask directly into a pre‑heated heating mantle, as thermal shock may cause the glass to crack or shatter. Allow the flask and heating mantle to heat up together gradually. The high‑temperature glass‑fibre liner reaches temperature quickly; allow the flask to warm slowly. Sudden temperature changes can cause dangerous glass fragmentation.
Magnetic Field Interference — Medical Devices: The stirrer contains strong permanent magnets. People with implanted medical devices (e.g., pacemakers, implantable cardioverter‑defibrillators, neurostimulators) should keep a safe distance of at least 30 cm from the operating stirrer. Do not place the instrument near credit cards, hard drives, computer monitors, or other magnetic‑sensitive equipment.
Electrical Safety — Proper Grounding: Do not operate the instrument with wet hands. Ensure the mains power cable does not come into contact with liquids or sharp edges that could damage the insulation. Use only the supplied grounded power cord and ensure the outlet provides proper grounding. Disconnect the power cord before cleaning, servicing, or moving the unit. Do not operate if the power cord is damaged. The IP21 rating offers protection against vertically falling water drops, but does not protect against immersion or significant liquid spills.
Starting Stirring — Smooth Acceleration: Always start stirring at a low speed (200‑300 rpm) and gradually increase to the desired level. A sudden high‑speed start may cause the stir bar to decouple, spin erratically, or strike the vessel wall, leading to splashing, spillage or vessel breakage. The brushless DC motor provides smooth acceleration, but operator caution is still required.
Chemical Compatibility — Ceramic Coating Limits: The ceramic‑coated aluminium work plate is resistant to strong acids, strong alkalis and organic solvents. However, prolonged exposure to some concentrated mineral acids (e.g., hydrofluoric acid, concentrated sulphuric acid) or aggressive organic solvents may degrade the coating. Clean spills promptly. Refer to the Safety Data Sheet (SDS) for specific chemicals. Never heat sealed vessels or containers that cannot vent pressure, as explosion may result.
Heating Mantle Contamination: If the inner glass‑fibre chamber of the heating mantle becomes contaminated with chemical spills, do not attempt to clean it. Once the insulation is saturated, the contamination cannot be removed, and the whole mantle may need replacement. Avoid heating substances that may produce corrosive vapours that can attack the fibre insulation.
Spill Management — Prevent Liquids Entering Housing: If a liquid spill occurs on the work plate or heating mantle during operation, turn off the heating and stirring functions immediately. Unplug the unit, allow the plate to cool (if heated) and wipe the spill clean with a soft, damp cloth. Do not let liquids seep under the work plate or into the housing. The IP21 rating does not protect against pooling liquids or immersion.
Operating Environment — Clean, Stable Benchtop: Use the instrument indoors only, on a stable, level, non‑flammable laboratory benchtop. Do not use in explosive atmospheres or in the presence of flammable gases or vapours. The permissible ambient temperature range is 5‑40 °C with relative humidity not exceeding 80 %. Allow at least 10 cm clearance on all sides for proper heat dissipation and ventilation. Do not cover the instrument during operation.
External PT1000 Sensor Safety — Secure Placement: When using the PT1000 external temperature sensor (included), insert the sensor probe into the sample vessel and secure it with a suitable stand and clamp (included). Do not allow the sensor cable to contact the hot work plate, as this may melt the wire insulation and cause sensor failure, electrical hazard or burns. If any abnormal situation is detected (e.g., sensor failure or disconnection, indicated by an error code on the display), the heating mode will automatically shut down as a safety precaution. Always inspect the sensor cable for damage before use.
Cleaning and Maintenance — Safe Cleaning Protocols: Unplug the unit and allow the work plate and heating mantle to cool completely before cleaning. Wipe the ceramic‑coated work plate and the metal housing with a soft, damp cloth using a mild laboratory detergent or 70 % isopropyl alcohol. Do not immerse the unit in liquid. Do not use abrasive cleaners or metal‑scouring pads that could scratch the ceramic coating. Do not saturate the fibre insulation inside the heating mantle with liquid; if contaminated, replace the mantle. The brushless DC motor requires no routine maintenance, but periodically inspect the power cord for signs of wear or damage.
Training Requirement — Qualified Users Only: Only trained laboratory personnel with appropriate technical background in hotplate stirrer and heating mantle operation should operate this instrument for clinical diagnostic or research applications. Users must read and understand the operator’s manual before first use. Laboratory managers should ensure all operators are aware of the proper procedure for starting and stopping stir bars, changing heating mantles, and the specific safety considerations for heating and stirring hazardous materials.

2. FIRST AID MEASURES

Burn from Hot Surface: If skin contacts the hot work plate, heating mantle, or a hot vessel, immediately cool the burn area with cool (not cold) running water for at least 15 minutes. Do not apply ice directly. Remove any jewellery or constrictive items from the affected area. Cover the burn with a sterile, non‑adhesive dressing. Seek medical attention for large‑area burns (larger than the palm of the hand), deep burns (white or charred appearance), or burns causing blistering. For burns on the face, hands, feet, or genitals, seek immediate medical attention.
Fire: If a fire occurs on or near the instrument, immediately turn off the power if safe to do so. Use a class ABC dry chemical fire extinguisher or carbon dioxide (CO₂) extinguisher. Do not use water on electrical fires. Evacuate the immediate area if the fire cannot be immediately controlled. Call emergency services.
Chemical Splash to Eyes: If a heated chemical sample or reagent splashes into the eyes, immediately flush the eyes with copious amounts of cool water or sterile saline for at least 15 minutes. Hold the eyelids open to ensure thorough rinsing. Remove contact lenses if present and easily removable. Seek immediate medical attention. Do not attempt to neutralise the chemical in the eye.
Chemical Splash to Skin: Remove contaminated clothing immediately. Flush the affected skin area with cool running water for at least 15 minutes. Do not rub or scrub. Seek medical evaluation for chemical burns or if irritation persists. Refer to the Safety Data Sheet (SDS) for the specific chemical involved.
Inhalation of Fumes: If fumes from heated chemicals are inhaled, move the affected person to fresh air immediately. Keep the person warm and at rest. If breathing is difficult, administer oxygen if trained. If breathing stops, perform CPR. Seek immediate medical attention.
Electrical Shock: If an electrical shock incident occurs, disconnect power at the circuit breaker before attempting to assist the victim. Do not touch the victim until the power is disconnected. Once safe, assess the victim for responsiveness and breathing. Call emergency medical services immediately. Perform CPR if trained and necessary. Seek medical evaluation for all electrical shock victims, even if symptoms appear mild.

3. FIRE FIGHTING MEASURES

Flammability — Primary Fire Hazard is Heated Chemicals: The instrument’s metal housing is non‑flammable, but the power cord, internal wiring, electronic components, and plastic control elements are combustible. The glass‑fibre inner sleeve and ceramic‑coated work plate are non‑flammable. The primary fire hazard is the flammable chemicals, solvents, or materials being heated in the flask or stirred on the work plate.
Extinguishing Media — Electrical Fires Require CO₂ or Dry Chemical: Use carbon dioxide (CO₂), dry chemical (ABC class), or alcohol‑resistant foam extinguishers for fires involving the electrical components or nearby flammable materials. Do not use water on electrical fires, as water conducts electricity and can cause electrical shock or damage the instrument.
Fire Response — Isolate Power and Evacuate: Immediately disconnect power to the instrument at the circuit breaker if safe to do so. Evacuate the immediate area. Use an appropriate fire extinguisher for small, contained fires. For larger fires, evacuate the laboratory and call emergency services. Do not attempt to extinguish a fire if not trained or if the fire is spreading rapidly.
Special Protective Equipment for Firefighters: Firefighters should wear self‑contained breathing apparatus (SCBA) and full structural firefighting gear (including gloves, boots, helmet, and turnout coat) when fighting fires in laboratory settings, as combustion products may include toxic fumes from burning plastics, chemicals, and electrical components.

SHORT DESCRIPTION

The LCD Digital Heating Magnetic Stirrer is a modular, medium‑capacity, and safety‑oriented benchtop instrument designed for precise, uniform medium‑to‑large‑volume heating and efficient mixing in clinical diagnostics, pharmaceutical QC, analytical chemistry, and industrial research.

Engineered with a quick‑change interchangeable heating jacket specifically for 500 mL round‑bottom flasks (inner diameter 118.75 mm), it can also be adapted for 100 mL, 250 mL, and 1000 mL flasks or beakers by simply swapping the mantle. The system offers a stirring speed range of 200 to 1500 rpm (±20 rpm) and controllable heating from 25 °C to 280 °C (±1 % / ±1 °C), with all parameters displayed on a high‑resolution LCD screen. The built‑in PID controller is supported by a temperature self‑calibration function and an external PT1000 port (±0.2 °C). When the heating mantle is detached, the same unit becomes a high‑power magnetic stirrer with a 20 L stirring capacity (water) on its ceramic‑coated work plate.

Overall dimensions are 295 × 160 × 160 mm, with a net weight of 3.7 kg. The system is TÜV‑certified (CE, cTUVus, FCC), IP21‑rated, and built with a fire‑resistant metal outer casing. Key safety features include dual independent safety circuits for redundant over‑temperature protection (420 °C hardware cutoff), a “HOT” warning indicator that remains active even after disconnection (>50 °C), and a safety lock to prevent accidental changes during operation. The brushless DC motor is maintenance‑ and spark‑free, and the instrument automatically saves the last used parameters.

For the clinical laboratory scientist, pharmaceutical QC chemist, and industrial production engineer, this instrument delivers the modular versatility and medium‑batch processing capacity required for trace element analysis (blood lead, urine cadmium), bulk gel melting, and large‑scale dissolution testing. For the patient, its reliable, accurate, and safe thermal processing ensures that life‑saving diagnostic tests and pharmaceutical therapies remain consistently reliable and reproducible.

3. PHYSICAL & OPERATIONAL PROPERTIES

Dual‑mode operation (“Two‑in‑One” mode): The instrument can be used in three independent configurations:

Mode 1 (Heating + Stirring on Mantle): The mantle provides simultaneous heating and stirring of the contents of the 500 mL round‑bottom flask.

Mode 2 (Stirring‑Only): The mantle can be detached, and the instrument functions as a standard 20‑litre magnetic stirrer on its φ135 mm ceramic‑coated work plate.

Mode 3 (Dual‑purpose Operation – Heat + Stir independently): One unit heats (using the heating mantle) while a separate, independent unit stirs (using the 20‑litre capacity work plate). This offers genuine two‑device‑in‑one capability, dramatically improving laboratory productivity.

Display: High‑contrast LCD digital display simultaneously shows set and actual values for temperature and speed, as well as timer status, providing complete operational visibility without toggling options.

Operation: Simple, intuitive digital controls with tactile buttons for temperature, speed and timer programming. Incremental 1 °C temperature adjustment and 1 rpm speed resolution allow precise setting of experimental parameters.

Stirring system: Powerful rare‑earth magnets provide strong magnetic coupling, preventing stir bar decoupling even with viscous liquids or at high speeds. The brushless DC motor provides stable torque and ultra‑quiet, vibration‑free operation.

Safety functions:

420 °C over‑temperature protection (hardware cutoff): A separate thermal cut‑off sensor shuts down heating if the work plate exceeds 420 °C, preventing runaway heating, fire hazards, and sample destruction even if the primary control system fails.

Spill protection: IP21‑rated metal housing offers protection against solid foreign objects >12.5 mm and vertically falling water drops. The fire‑resistant metal housing also provides protection against chemical spills and is easy to clean.

Portability: Compact benchtop design with a small footprint of 295 × 160 mm and light weight (3.7 kg), easily moved between workstations.

Maintenance: The brushless DC motor is maintenance‑free, requiring no routine brush replacement or lubrication. The ceramic‑coated work plate and metal housing are easy to clean with a mild detergent and soft, damp cloth.

Included accessories: The package includes the PT1000 external temperature sensor, support rod, support clamp and magnetic stirring bar.

4. STORAGE & HANDLING ATTRIBUTES

Operation with external sensor (PT1000): Insert the PT1000 temperature sensor probe into the sample vessel and secure it with the support clamp. Do not allow the sensor wire to contact the hot heating mantle, as this may melt the insulation and cause sensor failure or an electrical hazard.

Attaching and removing heating mantles: Ensure the driving unit is turned off and cool. The interchangeable mantle attaches via a dedicated connector. To remove after use, allow the mantle to cool completely (“HOT” indicator off) before disconnecting.

Independent dual‑purpose operation (“two‑in‑one mode”): To run the instrument as two separate devices (one heating on the mantle, one stirring on the base work plate), follow the manufacturer’s configuration instructions in the user manual.

Temperature self‑calibration: To perform a self‑calibration, follow the manufacturer’s procedure using a calibrated external thermometer.

Timer operation: Program the timer for the desired heating and stirring duration. When the timer reaches zero, the unit stops heating but continues stirring (if stirring was enabled), and the buzzer sounds. Press any button to silence the buzzer.

Cooling down: After use, turn off the power and allow the heating mantle to cool completely until the “HOT” indicator stops flashing (typically 30‑60 minutes, depending on operating temperature) before cleaning, moving, storing, or changing the mantle.

Periodic verification: Verify temperature accuracy periodically using a calibrated external thermometer. If deviation exceeds specifications (±1 °C <100 °C or ±1 % >100 °C), perform a temperature self‑calibration routine.
