The LCD Digital Heating Magnetic Stirrer (MS‑H280‑F100) is a modular, high‑safety, programmable benchtop instrument engineered for precise, safe, and versatile small‑volume heating and stirring in clinical diagnostics, pharmaceutical quality control, analytical chemistry, mining, and academic research laboratories. Featuring an interchangeable 100 mL round‑bottom flask heating mantle precisely contoured (inner diameter 72.75 mm) for standard 100 mL borosilicate round‑bottom flasks, this instrument can be configured as a dedicated 100 mL round‑bottom flask heater, or run in three independent modes: full heating and stirring, detached as a standard 20‑litre magnetic stirrer on its Ø135 mm ceramic‑coated work plate, or as a ‘Two‑in‑One’ system where one unit heats (using the heating mantle) while a separate, independent unit stirs (using the work plate) simultaneously. The heating system provides a temperature range of 25 °C to 280 °C (1 °C increments), a stirring speed range of 200–1500 rpm (1 rpm increments), and a high‑resolution LCD display for precise, real‑time parameter monitoring.

Every LCD Digital Heating Magnetic Stirrer (MS‑H280‑F100) features a high‑resolution LCD display showing set and actual values for temperature, speed and timer; a maintenance‑free, spark‑free brushless DC motor; and an alumina‑fibre heating mantle with aluminium‑silicate (ceramic) wool insulation for uniform heat distribution and a long service life. The instrument includes the PT1000 external temperature sensor (±0.2 °C accuracy), support rod, support clamp and magnetic stirring bar for precise control of the actual sample liquid temperature. A built‑in automatic temperature self‑calibration function further enhances accuracy for demanding applications. The programmable three‑step timer (1 min to 99 h 59 min) enables fully unattended, automated operation.

Key user‑focused features for small‑volume applications include interchangeable heating mantles for 100 mL, 250 mL, 500 mL and 1000 mL round‑bottom flasks (F series) and flat‑bottom beakers (B series), arbitrarily interchangeable; true “Two‑in‑One” independent operation; and a compact 3.7 kg footprint (295 × 160 mm).

Safety is exemplary with TÜV certification (CE, cTUVus, FCC), dual independent safety circuits providing redundant over‑temperature protection (420 °C hardware cutoff), an independent residual heat warning indicator (“HOT” flashes at >50 °C and continues even after the unit is turned off, including unplugged, until the mantle is safe to touch), and IP21‑rated housing with a fire‑resistant metal outer shell (Fireproof casing). Flask‑position detection safety will stop heating if the flask is out of position, preventing unsafe “dry” heating of the mantle.

For the clinical laboratory scientist, trace element analyst, and pharmaceutical QC chemist, the MS‑H280‑F100 delivers the modular versatility, small‑batch processing capacity, and high safety required for sample digestion for trace element analysis (blood lead, urine cadmium, heavy metals), small‑volume organic synthesis, dissolution testing and solid‑liquid extraction.

Description

LCD Digital Heating Magnetic Stirrer (MS-H280-F100)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Modular, High‑Precision Heating for 100mL Round‑bottom Flask Clinical Preparations
Primary Use: Provides a programmable LCD digital heating magnetic stirrer with a dedicated 100 mL round‑bottom flask heating mantle, fitted with a high‑performance alumina fiber sleeve (inner diameter 72.75 mm). Designed for the controlled, uniform heating and simultaneous stirring of small‑volume patient samples, reagents, and biological specimens in clinical diagnostics, pharmaceutical research, and academic laboratories. It features a maximum stirring capacity of 20 liters (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 from 25 °C to 280 °C in 1 °C increments. The high‑resolution LCD digital display simultaneously shows set and actual values for both temperature and speed.

How it helps: For the clinical chemist and laboratory scientist, the precisely contoured 100 mL round‑bottom flask heating mantle (inner diameter 72.75 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, and 100 mL to 1000 mL flat‑bottom beakers, which can be interchanged arbitrarily. The glass‑fibre inner sleeve with high‑quality aluminium‑silicate (ceramic) wool provides exceptional uniform heat distribution and corrosion resistance. The unit can 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. Sample Preparation, Trace Element Digestion and Organic Synthesis
Primary Use: The MS‑H280‑F100 is suitable for heating applications requiring a controlled environment, including sample preparations, digestions, organic synthesis, extraction, evaporation and distillation. For clinical chemistry workflows, it is used for the controlled digestion of patient serum, whole blood, urine, and tissue homogenates in strong acids at temperatures up to 280 °C, prior to trace element analysis by AAS or ICP‑MS.

How it helps: For the trace element analyst processing small‑volume patient samples, the 100 mL capacity is ideal for running high‑priority or rare clinical specimens (e.g., paediatric blood lead, neonatal urine cadmium, or kidney stone panel analysis) with minimal reagent use. The built‑in temperature self‑calibration function allows the user to correct for minor temperature deviations, ensuring exceptional measurement accuracy over time. The PT1000 external temperature sensor port (sensor, support rod and clamp included) provides ±0.2 °C accuracy for closed‑loop control of the actual sample liquid temperature – enabling complete, uniform oxidation of organic matrices even in demanding applications such as trace element and heavy metal panel analysis. Microprocessor‑controlled temperature regulation ensures that the controller maintains the sample temperature at the set point regardless of environmental fluctuations. For the patient undergoing heavy metal screening or nutritional deficiency monitoring, the accurate, controlled digestion achieved with the MS‑H280‑F100 results in precise and reliable clinical measurements, free from matrix interference, directly supporting correct diagnosis and treatment.

3. High‑Flexibility Dual‑Mode Benchtop Platform for Modern Diagnostic Testing
Primary Use: Can be used in three independent modes: as a complete heating and stirring unit (when the mantle is attached for 100 mL round‑bottom flask work), 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 heating 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 100 mL synthesis on the heating mantle while simultaneously stirring a 5‑litre beaker of phosphate‑buffered saline on the work plate dramatically improves productivity. A single instrument can process a 100 mL batch of critical patient digest, then be reconfigured for stirring tasks between runs – reducing equipment duplication and saving laboratory bench space. The integrated programmable three‑step timer (1 minute to 99 hours 59 minutes) can be set to stop heating while continuing to stir for safe unattended sample cooling. Large‑volume data display shows set values, actual values and timer status simultaneously on a high‑contrast LCD screen, enabling each operator to monitor the experiment without needing to switch screens and reducing the chance of protocol errors. For the patient, streamlined, standardised processing of QC materials 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 (Fireproof casing) with an interchangeable heating mantle. The heating mantle is constructed from a high‑quality aluminium‑silicate (ceramic) wool inner liner (alumina fiber 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 (F100 variant): Dedicated 100 mL round‑bottom flask heating mantle with an inner diameter of 72.75 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 / 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 (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 100 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 Ø135 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 and instrument utilisation in lean diagnostic laboratories.
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 at a glance without toggling options. The display shows large, high‑resolution characters for long‑distance viewing across the bench.
Operation: Simple, intuitive digital controls with tactile buttons for temperature, speed and timer programming. Incremental 1 °C temperature adjustment and 1 rpm speed resolution (1 rpm increments) allow precise setting of experimental parameters.
Heating technology: PID‑controlled heating with advanced microprocessor control 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.
Timer function: Programmable three‑step timer from 1 minute to 99 hours 59 minutes, with buzzer alert upon completion and safety‑lock parameter‑locking function. Upon completion (timer zero), the unit stops heating but continues stirring (if stirring was enabled), allowing the sample to cool gently while remaining under agitation and preventing thermal degradation of heat‑sensitive samples.
Safety value: safety is paramount and ensured by the flame‑retardant housing and compliance with IP21 and 420 °C over‑temperature hardware cutoff.
Safety functions:
- Safety lock: Prevents accidental changes to operating status once parameters are set.
- 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).
- 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 even if the primary control system fails.
- Flask‑position detection safety: The heating controller will detect when a flask is not correctly seated and will stop heating, preventing unsafe “dry” heating of the mantle.
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 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 typically includes the PT1000 external temperature sensor, support rod, support clamp and magnetic stirring bar.

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 device 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 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.
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 alumina‑fibre 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 (Fireproof casing), 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 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 (100 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 100 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 100 mL round‑bottom flask mantle (72.75 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 / smart sleeves: 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 external thermometer (PT1000). 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, small‑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 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 small‑batch and individual specimen format sample digestion for trace element analysis, small‑scale organic synthesis, dissolution testing and solid‑liquid extraction where precise, safe, and versatile heating with stirring is mandatory for diagnostic accuracy and patient safety.

SAFETY HANDLING PRECAUTIONS

1. 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.

2. 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.

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 100 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 Ø135 mm ceramic‑coated work plate.

Operation: Simple, intuitive digital controls with tactile buttons for temperature, speed and timer programming. Incremental 1 °C temperature adjustment and 1 rpm speed resolution (1 rpm increments) 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 value: safety is paramount and ensured by the flame‑retardant housing and compliance with IP21 and 420 °C over‑temperature hardware cutoff.

Safety functions:

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

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 even if the primary control system fails.

Flask‑position detection safety: The heating controller will detect when a flask is not correctly seated and will stop heating, preventing unsafe “dry” heating of the mantle.

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

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 device stops heating, displays an error message, and cuts off power, protecting the operator and preventing equipment damage.

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.

Fire Safety: Fire‑resistant metal housing (Fireproof casing), 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.

5. 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.

Temperature self‑calibration: To perform a self‑calibration, follow the manufacturer’s procedure using a calibrated external thermometer (PT1000). 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.
