Product Details
These tubes and caps are specifically designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene to ensure strength and clarity. The vials feature external threads that create a smooth and uniform inner surface, significantly reducing the risk of contamination. The screw caps, also made of polypropylene, have the same coefficient of expansion as the tubes, and when paired with a polypropylene inner lip, they guarantee a leakproof seal even under varying temperatures. The caps are equipped with a long skirt and a super-fast thread design, allowing for easy removal or sealing with just a single turn. Additionally, they are available with or without a silicone O-ring and come in a variety of colors, with screw caps sold separately.
