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.
