3. PHYSICAL & OPERATIONAL PROPERTIES

Construction: Durable, all‑metal aluminium alloy housing with a powder‑coated finish for excellent heat dissipation and chemical resistance. The four independent ceramic‑coated aluminium 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: Four independent Ø134 mm (5‑inch) ceramic‑coated aluminium 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: Four 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 four parallel experiments under different conditions simultaneously.
Motor technology: Four 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: Four 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 aluminium alloy housing also provides protection against chemical spills and is easy to clean.
Compact footprint: Ultra‑space‑saving design with 4 channels integrated into a single instrument (701 × 265 × 127 mm), significantly reducing bench space requirements compared to running four individual single‑channel instruments.
Maintenance: Each of the four brushless DC motors is maintenance‑free, requiring no routine brush replacement or lubrication. The four 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 EMC, FCC, ICES, cTUVus, CB, CE LVD, UKCA safety, and UKCA electromagnetic compatibility.
Dual Independent Safety Circuits: Two independent safety circuits continuously monitor the instrument. When overheating occurs, the sensor malfunctions, it will stop heating and sound an alarm. When a short circuit is detected, it will cut 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 four ceramic‑coated aluminium 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 aluminium alloy housing, ceramic‑coated work plates, and powder‑coated finish provide excellent fire protection.
Electrical Safety: Designed with four 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 aluminium 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 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 four 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 Channel 4 is 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.
