Safety caps, GL 45 threads

GL 45 safety 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.

Built-in stopcocks for easy interruption of solvent lines
Fit all bottles or canisters with DIN50 thread
Prevent evaporation of volatile compounds
Stopcocks rated up to 72 psi gas at 25 °C

: A bottom-sealing barbed adapter to connect ¹/₈" (3,2 mm) I.Ø tubing can be ordered separately.
