3. PHYSICAL & OPERATIONAL PROPERTIES

Construction: Durable, all‑metal housing with a powder‑coated finish for excellent heat dissipation and chemical resistance. The six independent ceramic‑coated aluminum work plates are each designed for rapid, uniform heat transfer and strong resistance to corrosion. IP21‑rated housing provides basic protection against solid foreign objects (>12.5 mm) and vertically falling water drops.
Work plates: Six independent Ø134 mm (5‑inch) ceramic‑coated aluminum discs, each providing fast heat transmission, strong corrosion resistance, and easy cleaning. The separate plates prevent cross‑contamination between channels and can accommodate a wide range of laboratory vessels, beakers, and heating blocks.
Display: Six independent high‑contrast LCD digital displays (one per channel) simultaneously show the actual temperature and stirring speed for each channel in real time, providing complete operational visibility without toggling between parameters or channels.
Operation: Simple, intuitive independent digital controls for each channel, with separate buttons for temperature setting, speed setting, and start/stop control. Each channel can be programmed with independent start/stop, temperature, speed, and display options, allowing the user to run up to six parallel experiments under different conditions simultaneously.
Motor technology: Six independent maintenance‑free, spark‑free brushless DC motors (one per channel) provide stable torque, extended life, and ultra‑quiet, vibration‑free operation. The brushless design requires no routine motor maintenance, and the spark‑free operation makes the instrument safe for use in environments where flammable solvents may be present.
Heating technology: PID temperature control technology provides real‑time precise control of the heating process. The instrument supports a heating temperature range from 25 °C to 280 °C (1 °C increments) with display accuracy of ±0.1 °C. Each channel can be heated independently, with rapid temperature ramp‑up to the set point using 600 W heating power per channel.
External sensor integration: Six independent PT1000 external temperature sensor ports (one per channel) enable direct closed‑loop control of the actual sample liquid temperature. When the optional PT1000 sensors are connected and placed in each sample vessel, the controller regulates the heater based on the actual sample temperature rather than the plate surface temperature, providing higher precision (±0.2 °C control accuracy) for sensitive applications.
Safety functions:
- Independent channel safety monitoring: Each channel is equipped with its own safety monitoring system, allowing the instrument to detect overheating, sensor failure, or electrical faults on a per‑channel basis while leaving unaffected channels operational.
- Dual independent safety circuits: Two independent safety circuits continuously monitor the entire instrument. If sensor failure, over‑temperature, or a short circuit is detected, the affected channel stops heating, an error message is displayed, and power is cut to ensure operator safety.
- 420 °C over‑temperature protection (hardware cutoff): A separate thermal cut‑off sensor for each channel 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.
- Residual heat warning (“HOT” indicator): For each channel independently, the “HOT” safety indicator activates when the respective work plate temperature exceeds 50 °C and continues flashing on the display even after the unit is turned off (including unplugged), alerting users to the dangerously hot surface until the plate is safe to touch.
Spill protection: IP21‑rated all‑metal housing offers protection against solid foreign objects (>12.5 mm) and vertically falling water drops. The powder‑coated housing also provides protection against chemical spills and is easy to clean.
Compact footprint: Ultra‑space‑saving design with 6 channels integrated into a single instrument (564 × 523 × 127 mm), significantly reducing bench space requirements compared to running six individual single‑channel instruments.
Maintenance: Each of the six brushless DC motors is maintenance‑free, requiring no routine brush replacement or lubrication. The six ceramic‑coated work plates are easy to clean with a mild detergent and soft, damp cloth.

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, CB, UKCA, ICES.
Dual Independent Safety Circuits: Two independent safety circuits continuously monitor the instrument. When overheating occurs or the sensor malfunctions, the instrument stops heating and sounds an alarm. When a short circuit is detected, it cuts off the power to ensure human safety. The reliable safety mechanism complies with IEC61010‑1, UL61010‑1, BSEN61010‑1, CAN/CSA‑C22.2 No.61010‑1, and all other safety regulations of laboratory heating devices, making the instrument competent for tasks without human surveillance.
Residual Heat Warning: The “HOT” safety indicator for each channel activates when the respective work plate exceeds 50 °C and continues flashing on the display even after the unit is turned off (including unplugged). This independent channel warning alerts users to a dangerously hot surface until the plate is safe to touch.
Over‑temperature Protection (Hardware): 420 °C hardware cutoff per channel prevents runaway heating and fire hazards, even if the primary control system fails.
Chemical Safety: The six ceramic‑coated aluminum work plates are resistant to strong acids, strong alkalis, and organic solvents, preventing corrosion and ensuring a long service life even when handling aggressive reagents such as concentrated acids for sample digestion.
Fire Safety: All‑metal housing, ceramic‑coated work plates, and powder‑coated finish provide excellent fire protection.
Electrical Safety: Designed with six independent brushless, spark‑free DC motors (explosion‑proof), making the instrument 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. The instrument is supplied with a calibration certificate and is backed by the 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 all channels to cool completely (verify each channel’s “HOT” indicator is off) before storage.
Installation: Place the instrument on a stable, level, non‑flammable, heat‑resistant laboratory benchtop away from flammable materials, volatile solvents, combustible gases, and 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 all work plates to cool completely before cleaning. Wipe each 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, which may scratch the ceramic coating.
Pre‑use inspection: Before each use, inspect the power cord and plug for any damage. Ensure all six work plates are clean, dry, and free of chemical residues. Verify that the correct heating blocks or vessels are properly seated on each channel. Check that the area is clear of flammable materials and that the instrument has adequate clearance (at least 10 cm) for heat dissipation.
Operation: For each channel independently: Place a stirring vessel (e.g., a beaker) centrally on the respective work plate and add a magnetic stir bar (maximum 40 mm length). Turn on the main power. Set the desired temperature (using the temperature control) and stirring speed (200–1500 rpm) via each channel’s independent digital controls. The independent LCD display for that channel will show the actual temperature and speed. Always start stirring at a low speed (200‑300 rpm) to allow the stir bar to couple correctly before gradually increasing to the target speed.
Operation with external sensors (PT1000, optional accessories): For precise sample temperature control on any channel, insert a PT1000 temperature sensor probe into the sample vessel on that channel and secure it with a suitable stand and clamp (sold separately). Do not allow any sensor cable to contact the hot work plate of its respective channel.
Independent channel operation: Each channel can be run independently. For example, Channel 1 can be set to heat to 100 °C and stir at 800 rpm, while Channel 2 heats to 200 °C and stirs at 500 rpm, Channel 3 operates as a stirrer only (no heat), and Channels 4–6 are turned off. This true independent parallel processing capability dramatically improves laboratory productivity.
Cooling down: After use, turn off the main power and allow all work plates to cool completely. Cooling time may take 30–60 minutes, depending on the operating temperature. Do not attempt to move, clean, or store the instrument until each channel’s residual heat warning (“HOT”) indicator has stopped flashing and the plates have cooled to a safe temperature.
Periodic verification: Verify the temperature accuracy periodically using a calibrated external thermometer or thermocouple for each channel independently. If deviation for any channel exceeds the specified tolerance (±1 °C <100 °C or ±1 % >100 °C), consult the manufacturer’s service guidelines for recalibration of that channel.

6. LABORATORY & CLINICAL APPLICATIONS

Primary Application: General‑purpose, 6‑channel independent heating and stirring for clinical diagnostics (trace element digestion for heavy metal testing), pharmaceutical quality control (parallel dissolution testing, multi‑sample preparation), analytical chemistry (reflux, distillation, Kjeldahl nitrogen determination), food and feed analysis, environmental testing, and academic research laboratories where multi‑parameter optimisation and truly independent parallel reaction control is required.
Clinical Role: A versatile and essential high‑throughput 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, food and feed analysis laboratories, environmental testing stations, soil and water treatment facilities, polymer research laboratories, and research institutions. Critical for parallel‑batch sample digestion for trace element analysis, multi‑condition dissolution testing, Kjeldahl nitrogen determination, Soxhlet extraction, and any application where running up to six independent experiments concurrently under precisely controlled, reproducible heating and stirring conditions is mandatory for diagnostic accuracy, regulatory compliance, and laboratory efficiency.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Burn Hazard — Hot Plates: Each of the six ceramic‑coated aluminum work plates can reach 280 °C and remain hot for an extended period after the power is turned off. Do not touch any work plate for at least 30–60 minutes after use, or until the residual heat “HOT” indicator for that channel has stopped flashing. Use appropriate heat‑resistant gloves or tools when handling vessels on any hot plate. Severe burns can occur upon contact. The “HOT” warning for each channel continues even after the unit is turned off (if still connected to mains) until that specific plate cools below 50 °C — always verify the indicator on each channel has stopped flashing before touching any plate.
Fire Hazard — Avoid Flammable Materials: Do not operate the hotplate stirrer 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 circuits (420 °C cutoff per channel) provide backup protection but should not replace operator vigilance.
Magnetic Field Interference: Each channel 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. The combined magnetic field from six active channels may be stronger than a single‑channel device.
Channel Independence and Vessel Spacing: The six channels operate independently. Ensure that vessels placed on adjacent channels do not touch or interfere with each other. The pre‑determined channel spacing (approximately 190 mm centre‑to‑centre) allows standard beakers up to 250 mL to 1000 mL capacity, but oversized vessels may crowd adjacent positions. Always allow sufficient clearance to prevent magnetic interference between channels and to avoid accidental contact with hot plates.
Vessel and Stir Bar Selection: Use only flat‑bottomed vessels (beakers, Erlenmeyer flasks, crystallising dishes) that sit flush on the ceramic‑coated work plates. Ensure each magnetic stir bar is in good condition without chips, cracks, or deformities and is properly centered in each vessel before starting. Do not exceed the maximum stir bar length of 40 mm per channel.
Start Slowly (Smooth Start): For each channel independently, 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. Because the six channels are independent, slowly increase speed on each channel sequentially.
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 basic protection against vertically falling water drops, but does not protect against immersion or significant liquid spills.
Chemical Compatibility — Ceramic Coating Limits: The ceramic‑coated aluminum work plates are resistant to strong acids, strong alkalis, and organic solvents. However, prolonged exposure to some concentrated mineral acids (e.g., hydrofluoric acid, concentrated sulfuric 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.
Spill Management — Prevent Liquids Entering Housing: If a liquid spill occurs on any work plate during operation, turn off the affected channel(s) immediately. Unplug the unit, allow the plate(s) to cool (if heated), and wipe the spill clean with a soft, damp cloth. Do not let liquids seep under the work plates or into the housing. The IP21 rating does not protect against pooling liquids or immersion.
Operating Environment — Clean, Stable Benchtop: Use the LCD Digital Hotplate Magnetic Stirrer 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 sensors (up to six, one per channel), insert each sensor probe into its respective sample vessel and secure it with a suitable stand and clamp (sold separately). Do not allow any sensor cable to contact the hot work plate of its channel, as this may melt the wire insulation and cause sensor failure, electrical hazard, or burns. If any sensor is disconnected or fails during operation (indicated by an error code on that channel’s LCD), the heating mode for that channel will automatically shut down as a safety precaution. Always inspect each sensor cable for damage before use.
Cleaning and Maintenance — Safe Cleaning Protocols: Unplug the unit before cleaning. Allow all work plates to cool completely (verify each channel’s “HOT” indicator has stopped flashing) before cleaning. Wipe each ceramic‑coated work plate and the aluminum alloy 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 ceramic coating. The brushless DC motors require no routine maintenance, but periodically inspect the power cord and the condition of each work plate for signs of wear or chemical damage.
Over‑Temperature and Short‑Circuit Protection (Redundant Safety per Channel): Each channel has dual independent safety circuits. If any work plate exceeds 420 °C, that channel will automatically stop heating and display an error message. If a short‑circuit is detected in a channel, the second safety circuit will cut off power to that channel. While these features provide redundancy, they are not a substitute for proper laboratory safety practices. Do not disable or bypass any safety features.
Residual Heat Warning — Active Even When Off: After powering off (if the unit remains connected to mains), each channel’s “HOT” indicator may continue flashing if its plate is above 50 °C. This warning is independent of the main power switch and alerts users to dangerously hot surfaces. Always verify that all six channel indicators have stopped flashing before assuming the instrument is safe to touch or clean.
Training Requirement — Qualified Users Only: Only trained laboratory personnel with appropriate technical background in hotplate stirrer operation should operate the LCD Digital Hotplate Magnetic Stirrer 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 independent channel control features, the proper procedure for starting and stopping stir bars across six channels, and the specific safety considerations for heating and stirring hazardous materials.

2. FIRST AID MEASURES

Burn from Hot Surface: If skin contacts a hot work plate or a hot vessel on any channel, 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 during operation on any channel, 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 aluminum alloy housing is non‑flammable, but the power cord, internal wiring, electronic components, and plastic control elements are combustible. The ceramic‑coated work plates are non‑flammable. The primary fire hazard is the flammable chemicals, solvents, or materials being heated or stirred.
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

Display: Six independent high‑contrast LCD digital displays (one per channel) simultaneously show the actual temperature and stirring speed for each channel in real time, providing complete operational visibility without toggling between parameters or channels.

Safety functions:

Independent channel safety monitoring: Each channel is equipped with its own safety monitoring system, allowing the instrument to detect overheating, sensor failure, or electrical faults on a per‑channel basis while leaving unaffected channels operational.

Dual independent safety circuits: Two independent safety circuits continuously monitor the entire instrument. If sensor failure, over‑temperature, or a short circuit is detected, the affected channel stops heating, an error message is displayed, and power is cut to ensure operator safety.

420 °C over‑temperature protection (hardware cutoff): A separate thermal cut‑off sensor for each channel 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 all‑metal housing offers protection against solid foreign objects (>12.5 mm) and vertically falling water drops. The powder‑coated housing also provides protection against chemical spills and is easy to clean.

Compact footprint: Ultra‑space‑saving design with 6 channels integrated into a single instrument (564 × 523 × 127 mm), significantly reducing bench space requirements compared to running six individual single‑channel instruments.

Maintenance: Each of the six brushless DC motors is maintenance‑free, requiring no routine brush replacement or lubrication. The six ceramic‑coated work plates are easy to clean with a mild detergent and soft, damp cloth.

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, CB, UKCA, ICES.

Over‑temperature Protection (Hardware): 420 °C hardware cutoff per channel prevents runaway heating and fire hazards, even if the primary control system fails.

Chemical Safety: The six ceramic‑coated aluminum work plates are resistant to strong acids, strong alkalis, and organic solvents, preventing corrosion and ensuring a long service life even when handling aggressive reagents such as concentrated acids for sample digestion.

Fire Safety: All‑metal housing, ceramic‑coated work plates, and powder‑coated finish provide excellent fire protection.

Quality Assurance: Each instrument is factory‑calibrated. The instrument is supplied with a calibration certificate and is backed by the 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 all channels to cool completely (verify each channel’s “HOT” indicator is off) before storage.
