Product Description
Run extractions without stopcock grease getting into your samples. The PTFE stopcock turns smoothly and resists solvents, and the wide stem bore lets the liquid column break when closed, so the stem drains fully and you get cleaner cuts between layers on every separation.
This listing is for Kimble catalog number 29048F-30: KIMAX Squibb Pear-Shaped Separatory Funnel With Glass Stopper, 30mL, Case of 4. Funnels are supplied with a PTFE stopcock and either a standard taper ground glass stopper or a polyethylene stopper.

LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
