Scienceware Spinbar Tapered Magnetic Stir Bars

Spinbar® round magnetic stirring bars offer excellent centering and smooth running characteristics. The pivot minimizes the contact area of the bar to the vessel, reduces friction and lessens marring of plastic containers. Steam autoclavable at 121° C (250° F) for sterile solution stirring applications. Narrowed tapered ends form a shape which acts as a pivot point, removing the need for a separate pivot ring. PTFE Teflon® coated magnetic stir bar is inert and ideal for stirring aggressive chemical solutions.
