GL45 caps seal to the bottle with an O-ring (EPDM) which is resistant to commonly used HPLC solvents.
If improved chemical resistance is required (e.g. for halogenated hydrocarbons), order an FEP-coated O-ring separately.
One port is suitable for 1/16in tubing.
All other ports can fit 1/8in and 1/16in OD tubing.
A bottom-sealing barbed adapter to connect a 1/8in (3.2mm) ID tubing can be ordered separately.
Unused ports should be closed with 1/4-28 plugs.
