Dynalon Micro Magnetic Stir Bars

Dynalon® Micro magnetic stir bars are available in white and various other colors for easy sample identification throughout your laboratory benchtops. Dynalon 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, PTFE thickness accounts for 18% of stir bar diameter. Note: Colored magnetic stir bars may leach out in to sample when used with extremely aggressive chemicals. If you are stirring more aggressive chemical samples, be sure to use white PTFE stir bars rather than the colored PTFE magnetic stir bars.
