Article number: 51323


  • Waters-certified containers


WAT062341 - Solvent Bottle Caps, 4L, 4/Pkg


All certified containers have GL 45 threads, which means that the thread size and neck opening are defined by this glass standard.   

The 4-L bottle cap has the correct outside diameter to create a good fit with the 500-mL and 1-L certified containers. 

WAT062479 - Bottle Caps, 1L, 4/Pkg are too small to fit the certified containers. The outside diameter of the 1-L caps is too small and will not create a good fit inside the certified-container bottle necks.
