All five units have a simple keyless chuck setup, with easy to change shafts. The speed is easy to adjust, with a lock button to prevent accidental changes. Constant and accurate speed is assured using a brushless motor and torque compensation technology.

Overhead stirrers are preferred over magnetic stirrers when dealing with larger sample sizes, or more viscous liquids that a magnetic stirrer might not thoroughly mix. Overhead stirrers are also more versatile for labs with multiple applications, as stirrer shafts can be easily switched. If you would prefer a magnetic stirrer take a look at our full range of laboratory stirring solutions.
