PYREX 125mL Cylindrical Separatory Funnel, Graduat

Corning These 125mL PYREX® cylindrical separatory funnels are graduated to show approximate capacity, have a micro-finish No. 2 Product Standard Polytetrafluorethylene (PTFE) stopcock and a strong, lightweight No. 22 Standard Taper glass stopper. The PTFE plug fits into the micro-finish barrel. The plug also reduces freezing problems and grease contamination. For replacement glass Standard Taper stoppers, see No. 7650; for PTFE stopcock plugs, see No. 7681. - COG
