3mL Vial Cap Covers & Click Caps

Add color to your vial collection with cap covers or click caps. Choose a pack of 10, 50 or 100 and the finish you want. These listings are covers; vials and contents are not included.

Not every vial labeled 3mL has the same closure. Match the existing cap’s shape and diameter to the exact cover before ordering. If you also use a storage case, check the covered vial’s total height and width so the lid closes freely.
