Description
The OS40?Pro LCD Digital Overhead Stirrer delivers reliable and precise stirring performance for demanding laboratory applications, including chemical synthesis, pharmaceutical research, and industrial mixing. It offers a broad speed range from 50?rpm up to 2200?rpm with ?3?rpm control accuracy, and its LCD display shows both set and actual speed as well as torque trends for real?time monitoring of changes in sample viscosity. Powered by a durable brushless DC motor, this overhead stirrer maintains constant speed even with viscosity variation and prevents accidental spillage thanks to smooth start?up and safety circuits that respond to overload or stall conditions. Additional features include remote PC control and data transmission, auto?restart after power loss, and strong torque capacity suitable for stirring up to 40?L of liquid.
