Chem Snap Caps, Colour Coded, 11mm

Chem Snap Caps™ may be snapped on and off by hand which eliminates the need for metal crimping and decapping tools, thus reducing potential hazards due to sharp aluminum edges. Large opening provides greater target area for needle penetration. These liner-less Chem Snap Caps™ are available with or without starburst. The starburst allows for easier needle penetration. These caps were developed to handle the most volatile sample providing a liquid airtight seal to the vial. Simply snap on the cap and an evaporation-proof seal of a crimp cap is achieved. Snap caps are color coded for easy sample identification.
