PTFE Stirrer Bar – This Plain economy stir bar features an ALNICO V magnetic core which is one of the most powerful permanent magnet alloys available. A stir bar (also known as a flea, spin bar, stirring bar or stirbar) is a magnetic bar used to stir a liquid mixture or solution, usually in a laboratory. The stir bar’s motion id driven by a separate rotating magnet or assembly of electromagnets (i.e. coils) located beneath the vessel containing the liquid.

A general purpose stir bar that provides better mixing than cylindrical stirrers. An Alnico V magnet is encapsulated with a two step process, compression and isostatic encapsulation, to eliminate cracks and porosity. Each stir bar is polished to reduce the potential for contamination.. . . . . .
