Description
Port Cap Adapter 1/4"-28 UNF flat bottom
Create a closed system with GL-45 safety port caps, which seal to a bottle with a secure Silicone O-ring resistant to common HPLC solvents. This cap helps avoid twisted tubing due to its free-spinning collar design. For a closed system, use the adapter with 1/8" OD tubing to seal one port and a vent filter in the other to allow for pressure changes and off-gassing.
