Description
The OS?T400?Plus Overhead Stirrer delivers robust and reliable mixing for medium to high?viscosity liquids in laboratory and production environments. It offers precision speed control with forward/reverse operation and automatic torque adjustment to maintain consistent stirring even as sample viscosity changes. An easy?to?read LCD screen displays speed, torque, timing, and temperature when using an external sensor, while programmable timer functions support extended mixing protocols. Built?in safety features such as overload protection and a safety lock prevent accidental changes during operation and help ensure secure, continuous stirring. The stirrer?s ?through?the?top? paddle design allows quick vessel changes, and audible alerts signal timers and error conditions. This overhead stirrer is suitable for large?scale experimental workflows, quality?control labs, and industrial mixing tasks.
