Vial Caps & Seals are available with a wide variety of septa & liners. Aluminum crimp seals have a larger opening to provide increased target area for needle penetration. Poly Crimp Seals permit an airtight seal by hand or use a standard crimping tool. Snap Top 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 metal edges.
