LabStock LB10-500 Separatory Funnel Glass Stopcock 500 mL Capacity

LabStock LB10-500 Separatory Funnel, Glass Stopcock, 500 mL Capacity

LabStock LB10-500 Separatory Funnel, Glass Stopcock, 500 mL Capacity - The standard lubrication is laboratory-grade high vacuum silicon grease. These funnels are made of borosilicate glass and have ground glass stoppers and stopcocks. Glass stopcocks are held into the bore with a rubber o ring and may be easily removed for cleaning and re-lubing as needed. Traditional glass stopcocks are ground precisely to fit into a bore hole at the base of the separator funnel. Our glass stopcocks are pre-lubed with a very thin film of this grease, and it should not come into contact with your compound. Pear-shaped design, widely used in organic chemistry for separating organic from aquatic products. This joint requires a thin band of lubrication to form tight seal, otherwise it will leak.
