This cap system eliminates the safety hazards associated with aluminum foil-wrapped solvent containers

The system includes a three-hole PTFE cap, PEEK™ combination inlet filter and sparger, ETFE flangeless nuts and ferrules, ETFE vent port plug, and FEP fluoropolymer resin tubing. Systems are available with or without a solvent bottle adapter that converts GL-45 mobile phase caps to standard 4L bottles for direct connection to an HPLC pump.
