SP Bel-Art Spinpak Teflon™ Magnetic Stirring Bar Assortment

Cylindrical magnetic stirring bars have great centering and smooth-running features. They also come with a small pivot ring in the center which can be removed to make them more versatile. The pivot ring reduces the contact area of the bar with the vessel, which in turn reduces friction and prevents damage to plastic containers.
