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, which provide a smooth and uniform inner surface that reduces the risk of contamination. The screw caps, also made of polypropylene, provide the same coefficient of expansion as the tubes, ensuring a leakproof seal even at changing temperatures due to a polypropylene inner lip. Caps are designed with a long skirt and a super-fast thread design that allows them to be removed or sealed with a single turn. Available options include screw caps with or without a silicone O-ring and a variety of colors. Screw caps are sold separately.
