Description
The OS?T40?Plus / OS?T60?Plus Overhead Stirrer delivers reliable, controlled mixing for medium to large sample volumes with adjustable stirring speed and programmable timing. Built with an intuitive LCD screen, the unit displays real?time speed, torque, timing, and temperature data, and supports an external temperature sensor for accurate sample monitoring. Its safety lock prevents accidental changes during operation, while the through?the?top paddle design makes container placement and removal simple. The stirrer maintains constant speed by automatically adjusting torque in response to changes in sample viscosity, and also allows forward/reverse rotation for versatile mixing patterns. Additional features include an audible buzzer for end?of?timer notifications and built?in safety protections for secure performance in laboratory workflows.
