Bulk Media Preparation

The  LCD Digital Heating Magnetic Stirrer is a modular, medium‑capacity, and safety‑oriented benchtop instrument designed for precise, uniform medium‑to‑large‑volume heating and efficient mixing in clinical diagnostics, pharmaceutical QC, analytical chemistry, and industrial research.

Engineered with a quick‑change interchangeable heating jacket specifically for 500 mL round‑bottom flasks (inner diameter 118.75 mm), it can also be adapted for 100 mL, 250 mL, and 1000 mL flasks or beakers by simply swapping the mantle. The system offers a stirring speed range of 200 to 1500 rpm (±20 rpm) and controllable heating from 25 °C to 280 °C (±1 % / ±1 °C), with all parameters displayed on a high‑resolution LCD screen. The built‑in PID controller is supported by a temperature self‑calibration function and an external PT1000 port (±0.2 °C). When the heating mantle is detached, the same unit becomes a high‑power magnetic stirrer with a 20 L stirring capacity (water) on its ceramic‑coated work plate.

Overall dimensions are 295 × 160 × 160 mm, with a net weight of 3.7 kg. The system is TÜV‑certified (CE, cTUVus, FCC), IP21‑rated, and built with a fire‑resistant metal outer casing. Key safety features include dual independent safety circuits for redundant over‑temperature protection (420 °C hardware cutoff), a “HOT” warning indicator that remains active even after disconnection (>50 °C), and a safety lock to prevent accidental changes during operation. The brushless DC motor is maintenance‑ and spark‑free, and the instrument automatically saves the last used parameters.

For the clinical laboratory scientist, pharmaceutical QC chemist, and industrial production engineer, this instrument delivers the modular versatility and medium‑batch processing capacity required for trace element analysis (blood lead, urine cadmium), bulk gel melting, and large‑scale dissolution testing. For the patient, its reliable, accurate, and safe thermal processing ensures that life‑saving diagnostic tests and pharmaceutical therapies remain consistently reliable and reproducible.
