Cap adapters easily connect NOWPak and NOWPak II containers directly to analytical HPLC instruments, preparative scale HPLC instruments, GPC instruments and other equipment using pumps or vacuum to supply solvent.

Cap Adapter for 1/4” Tubing

This adapter is suitable for use with high-flow pump or vacuum applications where sparging is not required. It comes with:

 • A cap closure and PTFE adapter with a 4” PFA elbow solvent fitting.

 • An FEP diptube with a 40-micron stainless steel frit to prevent drips while changing containers

The 1/4” elbow fitting can be replaced with any standard 1/4” male NPT fitting for adaptation to other tubing sizes.
