Product Details
These tubes and caps are specifically designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene that ensures both strength and clarity. The vials feature external threads, providing a smooth and uniform inner surface that minimizes the risk of contamination. The polypropylene screw caps, which possess the same coefficient of expansion as the tubes, are engineered to ensure a leakproof seal even under varying temperatures, thanks to a polypropylene inner lip. The caps come with a long skirt and a super-fast thread design, allowing for quick removal or sealing with a single turn. They are available with or without a silicone O-ring and come in a variety of colors, although it should be noted that screw caps are sold separately.
