Laboratory Equipment Manufacture Chemical Electric Overhead Stirrer
Overhead Stirrer adopts brushless motor with stable performance. Equipped with digital display, rotary knob and button control, supporting adjustable speed, timing function and real-time torque display. It supports external temperature sensor connection, with one-click lock and anti-tipping protection for safe operation. Suitable for medium & high viscosity liquid mixing in laboratory, pharmaceutical and chemical applications. Two models available for max mixing volume 50L and 100L.
This laboratory overhead stirrer features a high-efficiency brushless motor, delivering stable, low-noise stirring. Controlled by digital display, buttons and rotary knob, it realizes continuous speed adjustment with 10 rpm stepping and 0–24 hours timing function.
It supports external temperature monitoring, and integrates practical safety functions including one-click lock, tipping protection and torque value real-time display. The drill chuck accepts stirring shafts of 1–10 mm diameter. Two specifications are optional: OS-50Pro (max. 50 L mixing volume) and OS-100Pro (max. 100 L mixing volume). Widely applied in chemical, biological, pharmaceutical and cosmetic lab mixing tasks.
