Octagonal Stir Bar, PTFE
- Our PTFE octagonal stirring bars feature ALNICO V magnetic cores, one of the most powerful permanent magnet alloys available.
- Octagonal 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.
