Magnetic Stirring Bar Guide

Magnetic stirring is used in a number of common laboratory procedures, yet the importance of selecting the best stirring bar for each particular application is often overlooked. The size of the magnetic stirrer, vessel shape (including the opening of the vessel that the stirbar has to fit through), viscosity and abrasiveness of the materials should all be considered when choosing the size, shape and materials (coating and magnet) of the magnetic stirring bar in order to achieve effective, efficient stirring results.
