Magnetic Stir Bars
Magnetic stir bars (aka lab stirrers) are the key accessory for magnetic stirrers. Using the strange sorcery of magnetism, stir bars rotate within the host liquid to provide safe, efficient stirring.
Lab stirring bars are almost always PTFE-coated. PTFE provides sufficient resistance to most of the chemicals that might require stirring.
The real variety in stirring bars are the shapes. Our selection includes the usual cylindrical / round stir bars, but also available are octagonal, egg-shaped, and cross-head magnetic stir bars.
