These 11mm Snap Caps™ can be snapped on and off by hand, eliminating the need for metal crimping and decapping tools, and reducing potential hazards due to sharp aluminum edges.

• Large opening provides greater target area for needle penetration
• Color coded for easy sample identification

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. By snapping on the cap, an evaporation-proof seal of a crimp cap is achieved.
