High‑Temperature Hotplate

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. This instrument serves as an ideal entry‑point into professional high‑temperature hotplate stirring for clinical diagnostic labs and research institutions transitioning to digitally controlled equipment. For the patient, reliable, reproducible high‑temperature processing ensures that diagnostic tests for heavy metal toxicity, nutritional deficiencies, and pharmaceutical products remain accurate and consistent, directly supporting effective clinical decision‑making and patient safety.
