Product Details
These tubes and caps have been designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene, offering strength and clarity. The vial features external threads that create a smooth and uniform inner surface, reducing the risk of contamination. The screw caps, also made of polypropylene, maintain the same coefficient of expansion as the tubes, ensuring a leakproof seal even under varying temperatures, aided by a polypropylene inner lip. The caps include a long skirt and a super-fast thread design that permits removal or sealing with a single turn. Available options for the screw caps include versions with or without a silicone O-ring and in a variety of colors. Screw caps are sold separately.
