Magnetic Stirring Bars


Octagon White	Octagon Blue	Octagon Red	Octagon Yellow

Coated with PTFE, these stirring bars are corrosion and chemical resistant. Some are available in different colors for easy identification.

Octagon—Octagonal stirring bars are the most commonly used shape. They have a large surface area to generate more turbulence than round bars, so they stir up particles for better mixing.
