Applications
The spherical form is ideal for the use in narrow vessels like e.g. test tubes. When used in beakers, the ball magnetic stirring bar is pushed to the vessel wall by the centrifugal forces for good eccentric stirring.
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. Disposable Magnetic Stirring Bars Teflon PTFE
ball Alnico magnet stirring bars are useful for high temperature applications up to 274˚C (525˚F).
