Squibb funnel with a PFTE stopcock. The TFE stem attaches directly to the glass stopcock with O-Rings or other gaskets.

• Detachable G-14 or G-18 TFE drip tip

This unique separatory funnel is manufactured with a removable PTFE stem that virtually eliminates breakage normally associated with standard glass stem stopcocks. Glassware equipped with this PTFE stem can survive repeated forceful strikes to the stem without breakage.
