Product Description
Stir through a standard taper joint without grease or glass-on-glass wear. A PTFE bearing is self-lubricating and chemically inert, so it runs smoothly against the shaft and does not contaminate reaction mixtures, even with aggressive reagents. PTFE bearings are also easy to clean between runs.
