Separatory Funnels with PTFE Stopcock and Lower Stem Outlet

This separatory funnel facilitates the precise separation of immiscible liquids with its lower stem design for easy and controlled draining. Every funnel is equipped with a PTFE stopcock. Those with capacities ranging from 10 to 125 mL feature a 2 mm PTFE stopcock, while funnels with a capacity of 250 mL or more are fitted with a 4 mm PTFE stopcock. There's an option to select either a glass stopper or a PTFE stopper. The PTFE variant helps to minimize problems related to freezing and grease contamination. Made of borosilicate glass for its excellent chemical durability and mechanical strength. See SC152F for PTFE stopcock replacement parts. See SP19GH for glass stopper replacement parts.
