By Corning![Pyrex® Cylindrical Separatory Funnels with PTFE Stopcock](https://www.krackeler.com/tt/lg/graphics/0001/jpg/product.zoom.1200-1--5.jpg)
These Pyrex® cylindrical separatory funnels are graduated to show approximate capacity, have a micro-finish PS PTFE stopcock and a strong, lightweight ST hollow glass stopper. 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 plugs, see Cat.No. 1-7681.
