Product Details
These tubes and caps have been designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene to provide strength and clarity. The vials feature external threads, which create a smooth and uniform inner surface that minimizes the risk of contamination. The screw caps, made of polypropylene to match the coefficient of expansion of the tubes, include a polypropylene inner lip that ensures a leakproof seal even under varying temperatures. The caps are designed with a long skirt and a super-fast thread pattern that allows for easy removal or sealing with a single turn. They are available with or without a silicone O-ring and come in a variety of colors. Screw caps are sold separately, ensuring customization to meet specific needs.
