Canary-Safe™ Solvent Safety Products

CC1014 Canary-Safe Cap 4, GL45, 4 Standard OD Tubing Ports with Shut-Off Valves

GL45 Caps - with Shutoff Valves

Our GL45 mobile phase screw caps with shut off valves allow you to keep your pumps primed as the solvent bottles are replaced.  By moving the valve to the closed position, you create a closed system. There will be no air bubbles in your inlet lines and you will be able to refill your mobile phase bottles, remount the caps, turn on your pump, switch the valves, and return to your operating specifications.  No more priming your pumps!
