Our Magnetic Stir Bars feature ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available. Offered in many shapes from round, octagonal, egg-shaped and more, these PTFE-coated Magnetic Stir Bars resist harsh chemicals and are resistant to scratching and high temperatures.
There are several measures that should be noticed to increase the life span of magnetic stir bars. First, stir bars should be stored in pairs to maintain magnetic strength. Stir bars should not be stored in a random mass or dropped on a hard surface especially steel. PTFE thickness accounts for 18% of stir bar diameter.
