Stirrer Bearing, PTFE, Chem-Stir , Complete, 10mm, 45/50 Inner Joint

Grease-Free PTFE stirrer bearing designed for use under moderate vacuum applications. The bearing consists of a threaded glass adapter having an inner joint, a set of PTFE washer style bearings, a stainless steel spring, nylon alignment ring and Celcon® compression cap. The unique design of this bearing provides hours of continous vacuum operation, with a minimum of "flaking" of the PTFE bearing surfaces.
