Product Details
These tubes and caps are designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene to offer strength and clarity. The vials feature external threads that provide a smooth and uniform inner surface, minimizing the risk of contamination. The polypropylene screw caps maintain the same coefficient of expansion as the tubes, complemented by a polypropylene inner lip to ensure a leakproof seal even under varying temperatures. The caps are designed with a long skirt and a super-fast thread design, allowing for easy removal or sealing with a single turn. Caps are available with or without a silicone O-ring and come in a variety of colors, with screw caps sold separately.
