Key Features

Interchangeable Heating Sleeves: Modular sleeves accommodate 100 mL, 250 mL, 500 mL, and 1000 mL flat-bottom beakers (HB series) or round-bottom flasks (HF series).
Flexible Configuration: Use as an integrated heating magnetic stirrer, standalone magnetic stirrer, or heating sleeve.
Aluminum Silicate Fiber Insulation: High-efficiency thermal insulation delivers rapid, uniform heating and chemical resistance.
Precise PID Temperature Control: Wide heating range from 25 to 280°C with external PT1000 sensor support (±0.2°C accuracy).
Dual Independent Safety Circuits: Overheat safety cut-off at 420°C with “HOT” surface flashing warning above 50°C.
Brushless DC Motor: Spark-free, explosion-proof DC brushless motor delivers maintenance-free, stable stirring up to 1500 rpm.
Fireproof Metal Housing: Robust enclosure ensures maximum durability and operator protection in laboratory environments.

Applications

Essential for chemical synthesis, pharmaceutical research, petrochemical testing, food analysis, agricultural science, and academic laboratories requiring precise vessel heating and liquid agitation.
