Product Details
These tubes and caps are specifically designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene which provides both strength and clarity. The vials feature external threads that create a smooth and uniform inner surface, minimizing the risk of contamination. The screw caps, also made from polypropylene, have the same coefficient of expansion as the tubes, ensuring a leakproof seal even in varying temperatures. Additionally, the caps are designed with a long skirt and a super-fast thread that allows for quick removal or sealing with just a single turn. They are available with or without a silicone O-ring and come in a variety of colors, with screw caps sold separately.
