Chemical resistant PTFE material
Pivot rings help with the stability and vibration of the stir bar on uneven or curved vessel bottoms
Laboratory grade
Autoclavable
New, unused PTFE (also referred to as Teflon) material. Since PTFE is hydrophobic, has high corrosion resistance and is very non reactive, it's the high quality material for magnetic stirring bars. Our laboratory-grade stir bars are octagon shaped, with a pivot ring for decreased resistance. 1 each, 70mm long by 10mm wide (approximately 2.75 inches by 0.39 inches). Great for home brewing yeast mixing.
