ProSource Octagonal PTFE Stirring Bars feature ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available. The PTFE coating is chemically inert and will not contaminate or react with your reaction mixture.
- Spinning ring reduces contact area between stir bar and vessel, reducing friction and noise
- 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
