Magnetic Star Stirrer Bar - Star (8 teeth)

Star shaped magnetic stirring bars add speed and efficiency to mixing operations. The “+” shape creates a deep vortex and provides stable, quiet operation.

PTFE coated Alnico magnet with a star shape.

Coating

Stir bars are typically coated with PTFE, which can resist high temperatures and is generally chemically inert. For very high temperature applications, and applications where PTFE is not chemically compatible, there are glass-coated options available. These are also suitable for use with highly abrasive materials.

Magnetic Component

The magnetic component is typically made of ALCINO, an alloy of aluminium (Al), Nickel (Ni), and cobalt (Co), which is suitable for most applications. There are some stir bars available that use samarium cobalt, which will offer stronger coupling with the internal magnet of the stirrer and reduce the chance of the bar spinning out. These bars allow for greater torque and can be useful in applications where you have large volumes or high viscosity liquids.
