Magnetic Stir Bars - Octagon PTFE Coated

Octagon stir bar features an ALNICO V magnet core encapsulated in a low friction PTFE coating. Durable and inert, these stir bars are autoclavable. Octagonal stirring bars are the most commonly used shape for stirring small volumes in vessels such as vials, tubes and gradient makers.

Particularly useful for environmental testing and life science applications in which small sample volumes need to be prepared and evaluated. ALNICO V magnetic cores are one of the most powerful permanent magnet alloys available.
