Dynalon Egg-Shaped Magnetic Stir Bars

Dynalon® egg shaped magnetic stir bars are PTFE coated and provide excellent chemical resistance and intert stirring capability for almost every laboratory stirring applications. Dynalon magnetic stir bars feature ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available. Stir bars should not be stored in a random mass or dropped on a hard surface, especially steel. Stir bars should be stored in pairs to maintain magnetic strength. In general the PTFE coating around each magnetic stir bar accounts for 18% of stir bar diameter.
