3. PHYSICAL & OPERATIONAL PROPERTIES

Construction: The LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3) is constructed from a highly durable, transparent high‑borosilicate glass liner that resists thermal shock (sudden changes from hot to cold without breaking). The stainless steel base provides structural stability and corrosion resistance. A high‑temperature resistant protective outer shell prevents direct contact with the hot glass, reducing burn risk.
Bath / Work plate: The functional work area is the 3‑liter bath (Ø220 × 105 mm) made of borosilicate glass. The bath can be filled with water or oil and can accommodate a wide range of flasks, beakers, and reaction vessels. The transparent nature of the bath enables real‑time visual monitoring of reactions, sample conditions, and color changes without needing to remove the vessel or interrupt the experiment.
Display & User Interface: The high‑contrast LCD digital display simultaneously shows the set values and actual real‑time values for stirring speed (rpm), time (timer), and temperature (°C). This design gives the operator complete operational awareness at a glance. The instrument is controlled via intuitive touch buttons that provide audible feedback with each press. The working status indicator light is an additional safety feature: a green light indicates normal operation, a flashing green light indicates the unit is heating to the set point, and a red light signals an alarm condition.
Heating & Stirring Technology: The heating elements are arranged around the borosilicate glass bath, ensuring uniform heat distribution across the liquid medium. The unit's DC brushless motor is spark‑free, long‑life, and maintenance‑free, operating with low noise and stable running characteristics. The secondary stirring (i.e., the bath motor also rotates the magnetic stir bar inside the reaction vessel) provides “dual‑use” functionality for the bath liquid and sample, ensuring bath liquid and samples are heated uniformly. The reversible function allows for bidirectional stirring, which improves homogenization for viscous or two‑phase solutions.
Timer & Automation: The integrated programmable timer ranges from 1 minute to 99 hours 59 minutes. When the timer countdown finishes, the unit automatically stops heating (to prevent heat damage to the sample) but continues stirring, allowing the sample to cool gently while remaining under agitation. A buzzer alert (“beep beep beep”) sounds at the end of the timed run to notify the operator.
Safety Functions:
- Safety Lock: Prevents accidental changes to operating parameters once a program is started (or to avoid unintended settings).
- Residual Heat Warning (“HOT” indicator): When the plate temperature exceeds 50 °C, the heating is turned off, and the LCD display will flash “HOT” as a constant warning. Crucially, this warning continues to flash even after the operator has turned the main power OFF, alerting them until the unit has cooled down completely to a safe temperature.
- Over‑Temperature Protection: A separate, dedicated hardware circuit will cut power to the heater if the bath temperature reaches 350 °C, preventing runaway heating and fire.
- Multiple Hardware Protections: The LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3) includes dry‑burning protection (halts heating if bath fluid is insufficient), overcurrent protection, and ground fault protection. These are managed through two independent safety circuits that continuously monitor the device; if overheating, sensor failure, or short circuit is detected, the unit will cut power or stop heating.
External Sensor: The LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3) is equipped with a PT1000 external temperature sensor port. When this optional sensor (not always included) is connected, the controller will regulate heat based on the actual temperature of the liquid sample rather than just the bath temperature, providing a higher level of precision (display resolution 0.1 °C, accuracy ±0.2 °C).
Portability & Power: With a universal power supply (100–240 V, 50/60 Hz), the LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3) can be used in laboratories worldwide without external voltage converters. The unit is a benchtop system, weighing 6 kg, and has a small footprint (343 × 215 mm).
Maintenance: The brushless DC motor is maintenance‑free, eliminating the need for routine brush replacement or lubrication. The borosilicate glass liner is easy to clean with standard laboratory detergents.

User Safety: The residual “HOT” warning (flashing on display, even after power off) is a primary safety feature alerting the operator to a dangerous surface. The secondary stirring and transparent bath reduce the need to expose the operator to hot vapors, spills, or the need to open a bath cover. The high‑temperature resistant protective outer shell prevents direct contact with the hot glass.
Electrical & Component Safety: The spark‑free DC brushless motor is safe to use in environments with flammable solvents. The IP21‑rated housing protects against solid foreign objects (>12.5 mm) and vertically falling water drops, safeguarding internal electronics from small spills. The multiple built‑in protections (dry‑burn, overcurrent, ground fault) ensure failsafe operation even under adverse conditions.
Chemical Safety: The high borosilicate glass liner is highly resistant to a wide range of chemicals and can handle both water and oil without degradation. The stainless steel base is corrosion‑resistant and easy to clean. This robust construction ensures a long lifespan, even in demanding chemical environments.
Quality Compliance: Each instrument is factory‑calibrated; the timer function and timer‑based shut‑down, combined with optional PT1000 sensor support and data logging via the LCD display, support GLP compliance and full experiment documentation. The instrument is supplied with a factory calibration certificate.

5. STORAGE & HANDLING ATTRIBUTES

Storage: Store the instrument in a clean, dry, dust‑free environment at room temperature (15–30 °C). Before storage, ensure the unit has completely cooled and the “HOT” warning is no longer flashing.
Installation: Place the LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3) on a stable, level, non‑flammable, heat‑resistant laboratory benchtop with adequate ventilation and clearance. The instrument must be kept away from flammable materials, volatile solvents, and combustible gases.
Cleaning: Unplug the unit and ensure it has completely cooled before cleaning. Wipe the high borosilicate glass liner, stainless steel base, and protective outer housing with a soft, damp cloth using a mild laboratory detergent or 70 % isopropyl alcohol. For stubborn residues inside the glass bath, use a non‑abrasive cleaner appropriate for glass (no scouring powders). Do not immerse the electrical control unit in liquids or allow liquid to penetrate the housing.
Pre‑Use Inspection: Before each use, inspect the power cord and plug for any damage. Ensure the glass liner is free of cracks and debris. Confirm that the bath is filled with the appropriate level of water or oil before turning on the heating element (dry‑burn protection may activate otherwise). Check that the stir bar is present and in good condition.
Operation – General: Fill the bath with the appropriate heating medium (water or oil) to the indicated level. Place the reaction vessel into the bath, positioning it centrally. Add a magnetic stir bar to the sample vessel. Turn on the main power, set the desired temperature (via the touch buttons) and stirring speed (100–1500 rpm) on the LCD. The unit will begin heating and stirring.
Setting The Timer: Program the timer by accessing the timer menu on the control panel. The timer can be set for any duration from 1 minute to 99 hours 59 minutes. Once the countdown reaches zero, the heating will stop, but the stirring will continue.
Reactivating After Timer: To restart the heating after the timer expires, set a new timer input or turn the unit off and back on.
Operation with External Sensor: For precise control of the sample liquid temperature, connect a PT1000 external sensor, insert the probe into the sample vessel, and secure it. The controller will then regulate the heater based on the readings from this sensor.
Cool‑Down Regulation: The unit has no active cooling; after use, turn off the heating function. The bath will cool by natural convection. Do not attempt to add cold liquid to the glass bath to cool it, as the sudden temperature change could cause the glass to crack.
Periodic Verification: Periodically verify temperature accuracy using a calibrated external thermometer or thermocouple. Keep a record of such verifications as part of the instrument’s performance log.

Especially suited for applications where 3‑liter capacity, 220 °C temperature maximum, and a transparent, corrosion‑resistant water/oil bath are required.
Clinical Role: An essential instrument for clinical chemistry laboratories, pharmaceutical R&D & QC, analytical chemistry departments, forensic labs, and research institutions. Critical for digesting biological samples for trace element analysis, performing water‑ and oil‑based chemical reactions, QC testing, and preparing diagnostic reagents where uniform and observable heating is essential.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Burn Hazard — High Glass and Bath Medium Temperature: The heating bath can reach 220 °C, and the hot glass liner, stainless‑steel base and protective outer shell remain dangerously hot for an extended period after the power is turned off. Do not touch the glass liner, metal surfaces or heated bath medium for at least 30‑60 minutes after use, or until the residual heat “HOT” indicator stops flashing. Use appropriate heat‑resistant gloves, beaker tongs or vessel holders when handling vessels or removing them from the bath. Severe burns can occur upon contact.
Residual Heat Warning — Continues Even When Off: The “HOT” safety indicator activates when the bath medium temperature exceeds 50 °C and continues flashing on the LCD display even after the unit is turned off (if still connected to mains). This critical safety feature is independent of the main power switch and alerts users to a dangerously hot surface until the bath is safe to touch (temperature drops below 50 °C). Always verify that the “HOT” indicator has stopped flashing before touching the glass, metal or any part of the bath.
Fire Hazard — Avoid Flammable Materials and Dry‑Burn Condition: Do not operate the instrument near flammable materials, volatile solvents, combustible gases or paper products. Keep the work area clear of flammable substances. Heating temperature must be set at least 50 °C lower than the ignition point of the chemicals being used. Do not operate the bath without sufficient water or oil – dry‑burn protection will stop heating, but this should not replace operator vigilance. Do not leave the instrument unattended while operating at high temperatures without appropriate safety protocols.
Glass Breakage Hazard — Thermal Shock: The high‑borosilicate glass liner is resistant to thermal shock, but sudden, extreme temperature changes (e.g., adding a large volume of cold liquid to a hot bath, or pouring cold water over a hot glass liner) can still cause the glass to crack or shatter. Never add cold liquid to the glass bath to cool it – always allow natural convection cooling. Always allow the bath to heat up gradually from a starting temperature below 50 °C (or room temperature). Inspect the glass liner for cracks, chips or signs of mechanical damage before each use.
Over‑Temperature Protection — Dual Independent Safety Circuits: The instrument has dual independent safety circuits that continuously monitor device status. If the bath temperature exceeds 350 °C or a built‑in sensor malfunctions, the unit 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.
Vessel Selection — Proper Vessel Fit and Submersion: Use only heat‑resistant glassware (borosilicate glass such as Pyrex or Kimax) designed for high‑temperature water/oil bath applications. Ensure the vessel is stable, fully immersed to the appropriate depth, and does not touch the bottom, sides or heating elements of the glass bath. The maximum recommended flask capacity for the V3 model is 3 litres.
Magnetic Stir Bar and Coupling: Use only PTFE‑coated magnetic stir bars in good condition without chips, cracks or deformities. For the LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3), use stir bars up to 40 mm in length. Start stirring at a low speed (100‑200 rpm) to allow the stir bar to centre itself and couple correctly before gradually increasing to the target speed. Always centre the vessel over the magnetic drive before starting. If the stir bar decouples during operation, stop stirring immediately, allow the fluid to settle, and then restart at a low speed.
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.
Bath Medium Selection and Level Monitoring: Use only appropriate media: distilled or deionised water for water bath applications (≤100 °C) or heat‑transfer oil for oil bath applications (100‑220 °C). Do not use volatile oils or solvents that could create flammable vapours at elevated temperatures. Always verify that the bath medium level is sufficient before turning on the heater; the medium should completely cover the heating elements. The dry‑burn protection will shut off heating if the level is too low, but regular checking is essential.
Spill Management — Prevent Liquids Entering Housing: If a liquid spill occurs on the work plate or bath rim during operation, turn off the heating and stirring functions immediately. Unplug the unit, allow the bath to cool (if heated) and wipe the spill clean with a soft, damp cloth. Do not let liquids seep under the glass liner or into the control 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 optional PT1000 external temperature sensor (sold separately), insert the sensor probe into the sample vessel and secure it with a suitable stand and clamp. Adjust the probe tip so that it is correctly submerged but does not touch the bottom or side walls of the vessel. Do not allow the sensor cable to contact the hot glass bath, 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 glass liner and bath medium to cool completely before cleaning. Wipe the glass liner, stainless‑steel base and protective outer 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, metal scouring pads or sharp objects that could scratch the glass liner. 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 bath operation should operate this instrument for clinical diagnostic or research applications. Users must read and understand the operator’s manual before the first use. Laboratory managers should ensure all operators are aware of the potential for glass breakage (thermal shock), the correct handling of water vs. oil baths, and the specific safety considerations for heating hazardous materials and viscous samples.

2. FIRST AID MEASURES

Burn from Hot Surface: If skin contacts the hot glass liner, metal housing 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.
Oil Splatter (Hot Oil Bath): If hot oil splatters onto the skin, treat immediately as a thermal burn. Cool the affected area with cool running water for at least 15 minutes. Do not attempt to wipe off the hot oil before cooling. Remove contaminated clothing if not adhered to the skin. Seek medical evaluation for oil burns, as they can be deeper than water burns.
Fire: If a fire occurs on or near the instrument (particularly oil bath fires), immediately turn off the power if safe to do so. Use a class ABC dry chemical fire extinguisher, carbon dioxide (CO₂) extinguisher, or a Class B foam extinguisher rated for flammable liquid fires. Do not use water on oil fires or 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, bath medium 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 (or heated oils) 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 and Oil Bath Media: The instrument’s metal housing is non‑flammable, but the power cord, internal wiring, electronic components and plastic control elements are combustible. The high‑borosilicate glass liner is non‑flammable. The primary fire hazard is the flammable chemicals, solvents or oil bath media being heated. Heat‑transfer oils have specific flash points and can ignite if the bath operating temperature exceeds their rated maximum.
Extinguishing Media — Oil Bath Fires Require Class B Extinguishers: For fires involving the bath fluid (oil) or flammable solvents, use carbon dioxide (CO₂), dry chemical (ABC or BC class) or Class B foam extinguishers specifically rated for flammable liquid fires. Do not use water on oil fires, as water can spread burning oil and cause the fire to intensify. Do not use water on electrical fires.
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, electrical components and degraded heat‑transfer oils.

3. PHYSICAL & OPERATIONAL PROPERTIES

Safety Functions:

Safety Lock: Prevents accidental changes to operating parameters once a program is started (or to avoid unintended settings).

Over‑Temperature Protection: A separate, dedicated hardware circuit will cut power to the heater if the bath temperature reaches 350 °C, preventing runaway heating and fire.

Maintenance: The brushless DC motor is maintenance‑free, eliminating the need for routine brush replacement or lubrication. The borosilicate glass liner is easy to clean with standard laboratory detergents.

5. STORAGE & HANDLING ATTRIBUTES

Storage: Store the instrument in a clean, dry, dust‑free environment at room temperature (15–30 °C). Before storage, ensure the unit has completely cooled and the “HOT” warning is no longer flashing.

Installation: Place the LCD Digital Heating Magnetic Stirring Bath (MS‑H220‑V3) on a stable, level, non‑flammable, heat‑resistant laboratory benchtop with adequate ventilation and clearance. The instrument must be kept away from flammable materials, volatile solvents, and combustible gases.

Setting The Timer: Program the timer by accessing the timer menu on the control panel. The timer can be set for any duration from 1 minute to 99 hours 59 minutes. Once the countdown reaches zero, the heating will stop, but the stirring will continue.

Reactivating After Timer: To restart the heating after the timer expires, set a new timer input or turn the unit off and back on.

Operation with External Sensor: For precise control of the sample liquid temperature, connect a PT1000 external sensor, insert the probe into the sample vessel, and secure it. The controller will then regulate the heater based on the readings from this sensor.

Cool‑Down Regulation: The unit has no active cooling; after use, turn off the heating function. The bath will cool by natural convection. Do not attempt to add cold liquid to the glass bath to cool it, as the sudden temperature change could cause the glass to crack.

Periodic Verification: Periodically verify temperature accuracy using a calibrated external thermometer or thermocouple. Keep a record of such verifications as part of the instrument’s performance log.
