Chemglass Macro Stirrer Bearing for 10 mm Shaft with Tooled Lubricant Cup 24/40

The Chemglass CG-2071-01 Macro Stirrer Bearing is a specialized piece of glassware used to create a leak-tight seal around a rotating mechanical stirrer shaft in a reaction vessel. The lubricant cup allows for a non-volatile lubricant, such as a vacuum oil or high-purity grease, to be added to the bearing. This enhances the seal and reduces friction, which can significantly extend the bearing's life. This stirrer bearing is a fundamental tool for complex chemical syntheses. Its primary applications include organic and inorganic synthesis, and process development.
