Product Description
Replacing a worn bearing, broken shaft or damaged blade keeps a precision stirring setup running without buying a full new assembly. These replacement parts fit the 6 mm semi-micro stirrer assembly used with 14/20 glassware. Keeping a few spares on hand reduces downtime when a part is chipped, worn or lost during cleaning.
This listing is for Kimble catalog number 303861-0000: 6mm Precision Stirrer Assembly Replacement Parts, Stirrer Bearing, 14/20. Parts are made from borosilicate glass 3.3 and fluoropolymers. The range includes a 14/20 stirrer bearing, a 6 mm OD by 280 mm glass stirrer shaft and an 11 x 33 mm PTFE stirrer blade, so you can replace only the component that needs it. Inspect the bearing and blade regularly and replace them at the first sign of wear or leaking. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
