Magnetic Cross Stirrer Bar - Cross (4 teeth)

Magnetic Cross Stirrer Bar - Cross (4 teeth)

Cross shaped magnetic stirring bars add speed and efficiency to mixing operations. The "+" shape creates a deep vortex and gives stable, quiet operation.

The bar is a PTFE coated Alnico magnet with a cross 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 Alnico, an alloy of aluminium (Al), nickel (Ni) and cobalt (Co), which is suitable for most applications. Some stir bars use samarium cobalt, which gives stronger coupling with the internal magnet of the stirrer and reduces the chance of the bar spinning out. Those bars allow for greater torque and can be useful where you have large volumes or high viscosity liquids.
