Magnetic Stirrer Stirrer Bar - HL Series

Magnetic Stirrer Stirrer Bar - HL Series

Elliptical shaped magnetic stirring bars are particularly well suited for round bottom flasks. Thicker in girth than the L Series with more of a conical shape.The shape mimics that of a flask and ensures complete mixing. They also offer minimal contact when used in plastic containers.

PTFE coated Alnico magnet with a thick elliptical (oval) 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.
