Polystyrene plastic Snap Cap Vials offer great rigidity and glass-like clarity. The Polyethylene caps “snap” on and off quickly and easily. These convenient and economical plastic snap cap vials are great for storing benchtop accessories and field sampling. These are ASTM compliant. This line of efficiently priced vials comes in an array of colors and sizes, making it easy to find the perfect fit for your application. Each vial in this series comes with an EZ Open Snap-On cap that is a cinch to open. Our vials are packaged with the lids already on and ready to go. Our products and services are intended for pharmacies, clinics, laboratories, veterinaries and only legal medical growers – qualified patients, primary caregivers or coops or collectives – who cultivate edibles in compliance with the Compassionate Use.
