250mL Beaker Heater

The LCD Digital Magnetic Stirrer with Electric Heating Mantle (MS‑H280‑B250) is a modular, high‑safety benchtop instrument engineered for precise, versatile, and safe heating and stirring of medium‑volume liquids in clinical diagnostics, pharmaceutical quality control, analytical chemistry, and research laboratories. Featuring an interchangeable 250 mL beaker heating mantle (with an optional 250 mL round‑bottom flask mantle available), this instrument can be configured as a dedicated 250 mL beaker heater or detached to function as a standard 20‑litre ceramic‑coated magnetic stirrer. The heating system provides a temperature range of 25 °C to 280 °C (1 °C increments), a stirring speed range of 200 to 1500 rpm, and an LCD digital display for precise, real‑time parameter monitoring.

Every LCD Digital Magnetic Stirrer with Electric Heating Mantle (MS‑H280‑B250) features a high‑resolution LCD display showing set and actual values for temperature, speed, and timer; a maintenance‑free, spark‑free brushless DC motor; and a glass‑fibre heating mantle with aluminium‑silicate (ceramic) wool insulation for uniform heat distribution and a long service life. The PT1000 external temperature sensor port (±0.2 °C accuracy) enables precise control of the actual sample liquid temperature for sensitive digestions and reactions. A built‑in temperature self‑calibration function further enhances accuracy for demanding applications. The programmable timer (1 min–99 h 59 min), auto‑reverse stirring, and safety lock function allow fully automated, unattended operation with full documentation.

Safety is paramount with TÜV certification (CE, cTUVus, FCC), dual independent safety circuits providing redundant over‑temperature protection (420 °C hardware cutoff), an independent residual heat warning indicator (“HOT” flashes at >50 °C and continues even after the unit is turned off, including unplugged), and IP21‑rated housing with a fire‑resistant metal outer shell.

For the clinical laboratory scientist, trace element analyst, and pharmaceutical QC chemist, the MS‑H280‑B250 delivers the modular versatility (interchangeable 100 mL, 250 mL, 500 mL, and 1000 mL mantles are available as optional extras), medium‑batch precision, and high safety required for sample digestion for trace element analysis (blood lead, urine cadmium, heavy metals), agarose gel preparation (20–30 gels per batch), culture media melting, and dissolution testing. For the patient, the reliable performance of this instrument ensures that diagnostic tests and pharmaceutical products are accurate and reproducible, directly supporting effective clinical decision‑making, appropriate treatment selection, and patient safety.
