Lab grade polypropylene Hinged Vials are sterile, leak-proof and airtight.

The containers are manufactured in FDA approved Class 1000 and Class 100000 clean rooms. The containers are sterile by process and for most applications do not require a second means of sterilization. The containers are physically closed in the mold as part of the manufacturing process in clean rooms using Hepa-filtration systems, guaranteeing zero particulates larger than one half micron. They are non-absorptive and non-aersoling. The flip-top is integrally hinged to the container, allowing the user to open and close the container with one hand.
