Scienceware® Spinbar® Polygon Magnetic Stir Bars

Spinbar® polygon 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. PTFE Teflon® coated magnetic stir bars are inert and ideal for stirring aggressive chemical solutions. Steam autoclavable at 121° C (250° F) for sterile solution stirring applications.
