This mini tabletop centrifuge is perfect for use in small labs. Adjust the speed to fit your needs in 500-rpm increments from 1000 to 4000 rpm. Set the timer between 0 to 60 minutes in 1-minute increments and the centrifuge will automatically shut off when the time is up. The electronic user interface is simple and easy-to-use. Three rubber feet suction to the work-surface to reduce noise and provide stability.
