Description
The OS20?Pro LCD Digital Overhead Stirrer is a robust and versatile lab instrument engineered for demanding mixing tasks. It features a high?efficiency brushless DC motor that provides stable and consistent stirring even as fluid viscosity changes, and the bright LCD display allows real?time monitoring of speed and torque for precise control. Operating within a wide range of 50???2200?rpm with ?3?rpm accuracy, this stirrer delivers smooth operation with safety circuits to prevent accidental spillage or overload conditions. Additional functions include PC connectivity via RS232 for remote control and data transmission, and an auto?restart feature in case of power interruptions, making it suitable for extended or overnight experiments. With a maximum stirring capacity of 20?litres and a compact, durable build, the OS20?Pro is ideal for use in chemical synthesis, formulation labs, and quality control environments.
