PYREX® 125mL Squibb Glass Separatory Funnel with No. 2 PTFE Stopcock and No. 22 Polyethylene Stopper – 6404-125

The PYREX® 125mL Squibb Glass Separatory Funnel is a durable laboratory instrument designed for liquid-liquid extraction, solvent separation, and chemical sample preparation. Manufactured from laboratory glass, it features a pear-shaped body, a No. 2 PTFE Product Standard stopcock, and a No. 22 high-density polyethylene (HDPE) standard taper stopper. The chemically resistant PTFE stopcock fits into a micro-finished glass barrel, helping prevent sticking and eliminating the need for grease lubrication. Suitable for pharmaceutical laboratories, chemical testing facilities, biotechnology laboratories, research institutions, and educational laboratories.
