Our 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.

Stirring rods are available in two versions: Pure PTFE solid stirring rod with tapered end, and pure PTFE stirring rod with mild steel core. The stirring rod version with steel core can be bent into a permanent shape. Inert and will not scratch, use up to 280°C.
