Safety Caps – GL45 Threads

  • Built-in stopcocks for easy interruption of solvent lines
  • Fit all bottles or canisters with GL45 thread
  • Prevent evaporation of volatile compounds
  • 2, 3, and 4 ports available
  • Stopcocks rated up to 72 psi gas at 25°C

GL45 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.

Unused ports can be closed with the stopcock. All ports can handle 1/8" or 1/16" OD tubing. A bottom-sealing barbed adapter to connect 1/8" (3.2 mm) ID tubing can be ordered separately.
