Cylindrical Magnetic Stirrer Bar with Pivot Ring, Teflon (PTFE) Coated.

A magnetic stirrer, or magnetic mixer, is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it.

The pivot ring minimizes the contact area of the bar to the vessel, reduces friction and lessens marring of plastic containers.

Magnetic stirrers have advantage over motorized ones. They are quieter and more efficient. They have no moving external parts to break or wear out. For cleaning stir bars, you do not need lubricants which could be a reason of contamination of the product.
