PyrexPlus® Coated Squibb Separatory Funnels with PTFE Stopcock
By Corning
These PyrexPlus® Squibb pear-shaped separatory funnels have a protective PVC coating for longer product life and safety. Protective coating helps prevent glass from shattering and reduces spills, is autoclavable (121°C) and resistant to thermal shock. The funnels have PTFE PS stopcocks and strong, hollow ST glass stoppers. The PTFE plug fits into the micro-finish barrel. The plug also reduces freezing problems and grease contamination. For replacement glass ST stoppers, see Cat.No. 1-7650; for PTFE stopcock assemblies, see Cat.No. 1-7681. Do not place over direct heat or flame or heat above 121°C moist heat or 110°C dry heat.
