Pyrex® Cylindrical Separatory Funnels with ST Joints
By Corning
These 100mL Pyrex® cylindrical separatory funnels are graduated to show approximate capacity, have a micro-finish No. 4 PS PTFE stopcock and inner and outer 24/40 ST joints. The PTFE plug fits into the micro-finish barrel. The plug also reduces freezing problems and grease contamination. For replacement PTFE stopcock plugs, see Cat.No. 1-7681. This funnel is also a replacement part for organic chemistry kits Cat.No. 1-6949.
