Infrared Heating Magnetic Stirrer (MS7‑H280‑G)

The  Infrared Heating Magnetic Stirrer (MS7‑H280‑G) is a versatile, programmable benchtop instrument that combines a high‑performance magnetic stirrer with a full‑coverage infrared heating system on a 7‑inch (180×180 mm) glass ceramic work plate. By connecting optional interchangeable heating mantles (smart jackets), the same unit can securely heat round‑bottom flasks from 100 mL to 1000 mL or stir flat‑bottom beakers with a maximum capacity of 20 liters, making it ideal for distillation, reflux, sample digestion, buffer preparation, and general laboratory heating.
Every LCD 7‑inch Infrared Heating Magnetic Stirrer (MS7‑H280‑G) features a high‑resolution LCD display showing set and actual values for temperature, speed, and timer, a maintenance‑free brushless DC motor, and a glass ceramic work plate that resists strong acids and alkalis for easy cleaning. The full‑coverage infrared heating elements ensure uniform heat distribution up to 280 °C, and the optional PT1000 external temperature sensor (±0.2 °C accuracy) provides precise control of the actual sample liquid temperature.
Key user‑focused features include interchangeable heating mantle adapters for round‑bottom flasks (100 mL, 250 mL, 500 mL, 1000 mL), a programmable timer (1 minute to 99 hours 59 minutes), an RS232 interface for remote PC control and data logging, and a safety lock. Safety is paramount with dual independent safety circuits providing over‑temperature protection (340 °C hardware cutoff), an independent residual heat warning (“HOT” flashes at >50 °C and continues even after the unit is turned off), a spill drain channel, and IP21 protection.
For the research scientist, pharmaceutical chemist, and clinical laboratory technologist, the LCD 7‑inch Infrared Heating Magnetic Stirrer (MS7‑H280‑G) delivers the precise, safe, and versatile heating and stirring required for chemical synthesis, distillation, reflux, sample digestion for trace element analysis, buffer preparation, and drug dissolution testing. For the patient, reliable and reproducible heating ensures that diagnostic tests and pharmaceutical products are accurate and consistent, directly supporting effective clinical decision‑making, appropriate treatment selection, and patient safety.

LCD digital heating magnetic stirrer (MS7-H550-Pro)

The LCD digital heating magnetic stirrer (MS7-H550-Pro) is a powerful, professional-grade designed for laboratories demanding the highest level of temperature control and safety for sensitive sample preparation, chemical synthesis, and analytical testing. With a maximum operating temperature of 550°C and a stirring capacity of up to 20 liters, it is the ideal instrument for clinical diagnostic laboratories performing high-temperature trace element ashing, pharmaceutical research requiring high-boiling point reactions, and academic chemistry labs exploring advanced synthesis.
Every LCD digital heating magnetic stirrer (MS7-H550-Pro) is enabled by a high heating output of 1000W on a robust 7-inch (184×184mm) glass ceramic work plate for fast, uniform heating up to 550°C±1°C. The advanced PID temperature controller and a maintenance-free brushless DC motor ensure precise, reliable magnetic stirring from 100 to 1500 rpm with 1rpm resolution.
Key user-focused safety features include an adjustable independent safety temperature controller (settable from 100-580°C) which automatically cuts power for failsafe operation, dual over-temperature protection circuits, and a "HOT" warning indicator (>50°C) that remains active even when the unit is powered off. The RS232 interface enables remote PC control and data logging, supporting full experiment documentation and GLP compliance. The instrument also holds TÜV-certified safety approvals (CE, cTUVus, FCC) and is IP21 rated.
For the clinical toxicologist preparing patient samples for heavy metal analysis, the pharmaceutical chemist synthesizing a new drug compound, or the quality control scientist performing accelerated stability testing, the MS7-H550-Pro delivers the unparalleled thermal performance, precision, and safety required for success. For the patient, the unwavering reliability and reproducibility of this instrument ensure that diagnostic results, pharmaceutical products, and research data are of the highest standard, directly supporting effective disease management and treatment.

LED Digital Heating Magnetic Stirrer (MS7‑H550‑S)

The DLAB LED Digital Heating Magnetic Stirrer (MS7‑H550‑S) is a high‑temperature, entry‑level professional benchtop instrument engineered for accurate, safe, and efficient heating and stirring in clinical diagnostics, pharmaceutical quality control, analytical chemistry, and materials science. Featuring a 7‑inch (184 × 184 mm) glass ceramic work plate, this hotplate stirrer delivers a heating range from room temperature up to 550 °C adjustable in 5 °C increments and a stepless speed range from 0 to 1500 rpm for flexible, simple operation in demanding applications such as ashing for trace element analysis, high‑temperature chemical synthesis, and buffer preparation.
Every  LED Digital Heating Magnetic Stirrer (MS7‑H550‑S) is factory tested and supplied with a calibration certificate. The powerful 1000 W heating element and durable glass ceramic work plate provide rapid, uniform heat distribution across the entire 7‑inch surface. A bright LED digital display simultaneously shows the set and actual temperature for clear real‑time monitoring.
Key user‑focused safety features include an independent 580 °C over‑temperature protection sensor (hardware cutoff) that automatically shuts off heating to prevent fire hazards, a residual heat warning indicator that flashes on the LED display when the plate >50 °C and continues even after the unit is turned off to protect users from burn hazards, and IP21 protection for basic dust and splash resistance. The optional PT1000 external temperature sensor (±0.2 °C accuracy) enables precise control of the actual sample liquid temperature for sensitive applications. The aluminum alloy housing with a powder‑coated finish provides excellent heat dissipation and chemical resistance.
Simple, intuitive operation is achieved through two independent control knobs for stepless speed and temperature adjustment, minimizing training time in high‑volume clinical and teaching laboratories. Two independent temperature probes continuously monitor the system, and a microprocessor controller provides additional safety control with a heating cutoff through two independent probes.
The instrument is TÜV‑certified (CE, cTUVus, FCC) and manufactured under ISO 9001 and ISO 13485 quality management systems.
For the clinical laboratory scientist, toxicology analyst, pharmaceutical QC analyst, and graduate‑level teaching instructor, the LED Digital Heating Magnetic Stirrer (MS7‑H550‑S) delivers the high‑temperature performance, safety, and straightforward operation required for ashing and dry digestion for trace element analysis (blood lead, urine cadmium, heavy metals), high‑temperature denaturation, and large‑volume sample processing.
