Caps may be snapped on and off by hand which eliminates the need for metal crimping and decapping tools, thus reducing potential hazard due to sharp aluminum metal edges. Large opening top provides a greater target area for needle penetration. Linerless Snap Top Caps™ are available with or without starburst. Starburst allows for easy needle penetration. Snap Caps are color coded for easy sample identification. Caps can also be used on 12x32 mm Snap Seal™ vials.
GC Snap Top Caps were developed to handle the most volatile samples, providing a liquid airtight seal to the vial. Simply snap on the cap and an evaporation proof seal of a crimp is achieved. Caps can also be used on 12x32 mm Snap Seal™ vials.
