PYREX® 1000mL Squibb Glass Separatory Funnel with No. 4 PTFE Stopcock and No. 27 Polyethylene Stopper – 6404-1L

The PYREX® 1000mL Squibb Glass Separatory Funnel is a high-quality borosilicate glass laboratory instrument designed for liquid-liquid extraction, solvent separation, and chemical sample preparation. Featuring a pear-shaped glass body, a No. 4 PTFE Product Standard stopcock, and a No. 27 high-density polyethylene (HDPE) standard taper stopper, the funnel provides controlled liquid discharge and reliable separation of immiscible liquid phases. Its chemically resistant PTFE stopcock fits into a micro-finished glass barrel, reducing sticking and eliminating the need for grease lubrication. Suitable for pharmaceutical laboratories, chemical testing facilities, biotechnology laboratories, research institutions, and educational laboratories.
