Description

LCD Digital Magnetic Stirrer with Heating Mantle for Beaker (MS‑H280‑B1000)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Large‑Volume Modular Heating Mantle Design for High‑Throughput Clinical Sample Processing
Primary Use: Provides a fully programmable LCD Digital Magnetic Stirrer with Heating Mantle for Beaker (MS‑H280‑B1000) (inner diameter 118.75 mm) precisely contoured for standard 1000 mL borosilicate beakers, used for the controlled and reproducible heating and stirring of large‑volume clinical samples, reagents, and biological specimens in clinical diagnostics, pharmaceutical research, and analytical laboratories. It features a maximum stirring capacity of 20 litres (water) on its Ø135 mm ceramic‑coated aluminium work plate (when the mantle is detached), a speed range of 200 to 1500 rpm (±20 rpm), heating from 25 °C to 280 °C in 1 °C increments, and an LCD digital display that simultaneously shows set and actual values.

How it helps: For the clinical laboratory scientist and pharmaceutical chemist, the 1000 mL heating mantle capacity enables the processing of large‑volume patient samples, batch chemical synthesis, and bulk reagent preparation in a single run. The intelligent interchangeable heating sleeve design allows flexible configuration with 100 mL, 250 mL, 500 mL, or 1000 mL round‑bottom flasks, as well as 100 mL, 250 mL, 500 mL, or 1000 mL flat‑bottom beakers, which can be interchanged arbitrarily. The precise 118.75 mm inner diameter ensures a form‑fitting contact with the 1000 mL beaker, maximising heat transfer efficiency. The glass‑fibre inner sleeve with high‑quality aluminium‑silicate (ceramic) wool provides uniform thermal distribution and corrosion resistance, ensuring even heating without localised hot spots. The unit also can be used as two independent devices – one for heating (using the mantle) and one for stirring (using the work plate) – a genuine two‑in‑one design that dramatically improves instrument utilisation in lean diagnostic laboratories. For the patient, the reproducibility, large‑volume capacity, and thermal uniformity of the platform ensure consistent conditions for bulk diagnostic sample preparation, supporting accurate test results even at high throughput.

2. High‑Volume, High‑Precision Temperature Control for Trace Element Digestion and Sample Preparation
Primary Use: Used for the controlled digestion of large‑volume patient samples – including 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, with the optional PT1000 sensor, support rod, and clamp included with the package.

How it helps: For the trace element analyst processing high‑volume patient samples in toxicology and occupational health screening, the 1000 mL capacity supports the simultaneous digestion of up to 10–20 individual specimens in a single run, significantly reducing total preparation time for batch testing. The PT1000 external temperature sensor (±0.2 °C accuracy) enables the instrument to regulate the actual temperature of the acid digest directly, ensuring complete, uniform oxidation of organic matrices even in demanding applications such as blood lead, urine cadmium, and heavy metal panel analysis. The integrated temperature self‑calibration function allows the user to correct for minor temperature deviations, ensuring measurement accuracy over time. For the patient undergoing heavy metal screening as part of occupational health monitoring or assessment of suspected poisoning, the accurate, high‑volume digestion of patient samples directly supports reliable test results and correct clinical decision‑making.

3. Benchtop Gel Melting and Bulk Culture Media Preparation for High‑Throughput Molecular Diagnostics and Clinical Microbiology
Primary Use: Enables the safe, uniform heating and melting of large volumes of solid or semi‑solid culture media, nutrient agars, and agarose gels directly in 1000 mL beakers or 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 samples, the 1000 mL capacity enables the preparation of 80–100 standard agarose gels or 200–250 culture plates in a single batch, dramatically improving laboratory throughput. The glass‑fibre and aluminium‑silicate wool inner sleeve provides 500 °C thermal resistance and superior heat retention, allowing solid media to melt evenly without localised scorching that could degrade nutrients. The auto‑reverse stirring function (programmable via the LCD panel) can be activated to improve homogenisation of media ingredients, preventing sedimentation and ensuring uniform distribution. The programmable timer (1 minute to 99 hours 59 minutes) delivers a buzzer alert on completion, while the safety lock parameter‑locking function prevents unintended changes to operating conditions during extended runs. 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 Clinical Quality Control and Bulk Buffer Preparation
Primary Use: The instrument can be used in two independent modes: as a complete heating and stirring unit (when the mantle is attached for 1000 mL beaker work) or as a stirring‑only unit on its 20‑litre capacity ceramic‑coated work plate (when the mantle is detached). The heat‑only and stir‑only functions can be programmed to run simultaneously for two distinct tasks, with the timer set to stop heating while continuing to stir for safe unattended sample cooling.

How it helps: For the clinical quality control manager and laboratory supervisor, the ability to run a 1000 mL beaker digest on the heating mantle while simultaneously stirring a 5‑litre beaker of phosphate‑buffered saline on the work plate dramatically improves productivity. This versatile design means a single instrument can process an entire week’s batch of QC standards, then be reconfigured for stirring tasks between batch runs, reducing equipment duplication. The 420 °C over‑temperature protection and residual heat warning system (flashing “HOT” on the LCD even after the unit is turned off and unplugged) ensure safe operation regardless of which mode is in use. The instrument is TÜV‑certified with CE, cTUVus, and FCC safety approvals, providing confidence in busy clinical laboratory environments. For the patient, streamlined, standardised processing of QC materials and buffers means fewer procedural errors across high‑volume sample runs, supporting faster, more accurate diagnostic test results.

3. PHYSICAL & OPERATIONAL PROPERTIES

Construction: Durable, fire‑resistant metal outer housing with an interchangeable heating mantle. The heating mantle is constructed from a glass‑fibre inner sleeve and high‑quality aluminium‑silicate (ceramic) wool, 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 (B1000 variant): Dedicated 1000 mL beaker 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 glass‑fibre and aluminium‑silicate wool liner provides superior heat retention and resistance to thermal shock.
Interchangeable heating mantles (smart sleeves): The driving unit can be flexibly configured with interchangeable heating sleeves for 100 mL, 250 mL, 500 mL, and 1000 mL round‑bottom flasks (MS‑H280‑F series), as well as 100 mL, 250 mL, 500 mL, and 1000 mL flat‑bottom beakers (MS‑H280‑B series), which can be interchanged arbitrarily. This 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 MS‑H280‑B1000 can be configured to run as two independent units simultaneously:
- Mode 1 (Heating + Stirring on Mantle): The mantle provides simultaneous heating and stirring of the contents of the 1000 mL beaker.
- Mode 2 (Dual‑purpose Operation – Heat + Stir independently): One unit heats (using the 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.
- Mode 3 (Stirring‑Only): The mantle can be detached, and the instrument functions as a standard 20‑litre magnetic stirrer on its Ø135 mm ceramic‑coated work plate.
Display: High‑resolution LCD digital display simultaneously shows set and actual values for temperature and speed, as well as timer status, providing complete operational visibility at a glance.
Operation: Simple, intuitive digital controls with tactile buttons for temperature, speed, and timer programming, plus a safety lock to prevent accidental changes to operating status.
Heating technology: PID‑controlled heating with built‑in temperature self‑calibration function; the customer‑accessible calibration routine allows the user to correct for minor temperature offsets, ensuring higher and more reproducible temperature 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.
Timer function: Programmable timer from 1 minute to 99 hours 59 minutes, with buzzer alert upon completion. The safety‑lock parameter‑locking function prevents unintended changes to operating conditions during extended runs.
Auto‑reverse stirring: When activated, the direction of rotation automatically reverses at a programmed interval, improving mixing efficiency for viscous or colloidal solutions and preventing the formation of a central vortex.
Safety functions:
- Safety lock: Prevents accidental changes to operating status once parameters are set.
- Residual heat warning: “HOT” indicator flashes when the heating mantle (or work plate) exceeds 50 °C and continues flashing even after the instrument is powered off (including unplugged) until the surface cools to a safe temperature (plate below 50 °C).
- Dual independent safety circuits: Two independent safety circuits continuously monitor system status; if sensor failure, over‑temperature (>420 °C), or short circuit is detected, heating stops automatically, an error message is displayed, and power is cut.
- 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.
- Flask‑position detection: The heating controller can sense when a flask is not correctly seated and stops heating, preventing unsafe “dry” heating of the mantle (inquiry recommended for specific implementation).
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 footprint of 295 × 160 mm, weight 3.7 kg, easily moved between workstations as required.
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 typically includes the PT1000 external temperature sensor, support rod, and clamp.

4. SAFETY & COMPLIANCE ATTRIBUTES

Regulatory Status: General laboratory equipment for in vitro diagnostic (IVD) use; manufactured under ISO 9001 and ISO 13485 quality management systems. TÜV‑certified safety: CE, cTUVus, FCC.
Dual Independent Safety Circuits: Two independent safety circuits continuously monitor the device. In case of overheating, sensor failure, or an electrical fault, the machine stops heating, displays an error message, and cuts off power, protecting the operator and preventing equipment damage.
Residual Heat Warning: The “HOT” safety indicator activates when the work plate (or 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).
Over‑temperature Protection (Hardware): 420 °C hardware cutoff prevents runaway heating and fire hazards, even if the primary control system fails.
Flask‑Position Detection Safety: The heating controller can detect when a flask is out of position and automatically stops heating, preventing unsafe “dry” heating of the mantle (confirm with manufacturer).
Chemical Safety: The ceramic‑coated aluminium work plate and the fire‑resistant metal outer housing are resistant to strong acids, strong alkalis, and organic solvents. The glass‑fibre and aluminium‑silicate wool inner sleeve of the heating mantle is chemically resistant and will absorb small chemical spills without short‑circuiting the heating element.
Fire Safety: Fire‑resistant metal housing, glass‑fibre insulation, and a non‑flammable ceramic‑coated work plate provide excellent fire protection.
Electrical Safety: Designed with a brushless, spark‑free DC motor (explosion‑proof), making it safe for use in environments where flammable solvents may be present. The IP21‑rated housing offers protection against solid foreign objects (>12.5 mm) and vertically falling water drops.
Quality Assurance: Each instrument is factory‑calibrated, and the built‑in temperature self‑calibration function may be used by the customer to adjust the internal offset for improved precision. The unit is supplied with a calibration certificate and is backed by a 2‑year manufacturer’s warranty.

5. 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 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 (1000 mL) is fitted for the beaker being used. Check that the beaker is dry, free of cracks, and properly seated in the mantle for maximum surface contact.
Beaker selection for heating mantle: Use only standard 1000 mL beakers (or round‑bottom flasks for F‑series mantles) 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 1000 mL beaker 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 stand 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. 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 (“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. This dual‑mode functionality dramatically increases laboratory productivity.
Temperature self‑calibration: To perform a self‑calibration, follow the manufacturer’s procedure using a calibrated reference thermometer. This adjusts the internal offset to correct for minor temperature deviations and maintain measurement accuracy over time.
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. The timer can also be deactivated if not needed.
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 or consult the manufacturer’s service guidelines for recalibration.

6. LABORATORY & CLINICAL APPLICATIONS

Primary Application: General‑purpose, large‑volume heating and stirring for clinical diagnostics (trace element digestion for heavy metal testing, bulk reagent preparation), pharmaceutical quality control (dissolution testing, large‑batch buffer preparation), analytical chemistry (reflux, distillation, solvent evaporation), mining and geochemistry, and research laboratories where the ability to heat both 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 batch‑format sample digestion for trace element analysis, agarose gel preparation (80–100 gels per batch), bulk culture media preparation (200–250 plates per batch), and small‑volume 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 (including unplugged). 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 Beaker Fit: Use only standard 1000 mL beakers 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 1000 mL beaker mantle (118.75 mm) is specifically designed for a snug, secure fit. A loose‑fitting beaker can cause uneven heating and create a fire hazard.
Thermal Shock — Gradual Heating Only: Do not place a cold beaker directly into a pre‑heated heating mantle, as thermal shock may cause the glass to crack or shatter. Allow the beaker and heating mantle to heat up together gradually. The high‑temperature glass‑fibre liner reaches temperature quickly; allow the beaker 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.
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 beaker 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.

3. PHYSICAL & OPERATIONAL PROPERTIES

Dual‑mode operation (two‑in‑one mode): The MS‑H280‑B1000 can be configured to run as two independent units simultaneously:

Mode 1 (Heating + Stirring on Mantle): The mantle provides simultaneous heating and stirring of the contents of the 1000 mL beaker.

Mode 2 (Dual‑purpose Operation – Heat + Stir independently): One unit heats (using the 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.

Mode 3 (Stirring‑Only): The mantle can be detached, and the instrument functions as a standard 20‑litre magnetic stirrer on its Ø135 mm ceramic‑coated work plate.

Display: High‑resolution LCD digital display simultaneously shows set and actual values for temperature and speed, as well as timer status, providing complete operational visibility at a glance.

Operation: Simple, intuitive digital controls with tactile buttons for temperature, speed, and timer programming, plus a safety lock to prevent accidental changes to operating status.

Heating technology: PID‑controlled heating with built‑in temperature self‑calibration function; the customer‑accessible calibration routine allows the user to correct for minor temperature offsets, ensuring higher and more reproducible temperature 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.

Timer function: Programmable timer from 1 minute to 99 hours 59 minutes, with buzzer alert upon completion. The safety‑lock parameter‑locking function prevents unintended changes to operating conditions during extended runs.

Auto‑reverse stirring: When activated, the direction of rotation automatically reverses at a programmed interval, improving mixing efficiency for viscous or colloidal solutions and preventing the formation of a central vortex.

Safety functions:

Safety lock: Prevents accidental changes to operating status once parameters are set.

Residual heat warning: “HOT” indicator flashes when the heating mantle (or work plate) exceeds 50 °C and continues flashing even after the instrument is powered off (including unplugged) until the surface cools to a safe temperature (plate below 50 °C).

Dual independent safety circuits: Two independent safety circuits continuously monitor system status; if sensor failure, over‑temperature (>420 °C), or short circuit is detected, heating stops automatically, an error message is displayed, and power is cut.

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.

Flask‑position detection: The heating controller can sense when a flask is not correctly seated and stops heating, preventing unsafe “dry” heating of the mantle (inquiry recommended for specific implementation).

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 footprint of 295 × 160 mm, weight 3.7 kg, easily moved between workstations as required.

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 typically includes the PT1000 external temperature sensor, support rod, and clamp.
