Magnetic Stirrer - an overview ScienceDirect Topics

A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example. A magnetic stirring system generally includes a coupled heating system for heating the liquid (Figure 6.5).

Deciding Between a Magnetic Stirrer and an Overhead Stirrer

Jun 06, 2019 With a magnetic stirrer, the stir bar size is also important. The stir bar should be roughly the same length as the internal drive magnet to prevent decoupling and spinout (when the bar loses its coupling and stops spinning altogether). When using a magnetic stirrer, note that there are often recommendations for maximum stir bar size. ...

Mar 07, 2013 For egg-type stir bars in round bottom flasks, the concavity of the surface will help, but not eliminate 'flinging'.If you need a fast stir, you need a bigger stir bar. Personally, I've never needed larger than 3/4 because of my use preference, (also do not typically use roundbottoms larger than 1L). Ultimately, however, remember stir bars are ...

May 17, 2018 The size of the magnet inside the stirrer, which may be referred to as the drive magnet, is of great importance when choosing a stir bar size. The length of the bar should be about equal to the magnet size to avoid spinout. Spinout occurs when the bar loses its coupling with the internal magnet of the stirrer and the bar stops spinning altogether. Stir bars …
