Product Details
These tubes and caps have been designed for the storage and transportation of biological material. They are manufactured from non-toxic polypropylene, offering strength and clarity. The vials have external threads, which provide a smooth and uniform inner surface that reduces the risk of contamination. The screw caps, made of polypropylene, provide the same coefficient of expansion as the tubes, ensuring a leakproof seal even at changing temperatures due to the polypropylene inner lip. The caps feature a long skirt and a super-fast thread design that allows them to be removed or sealed with a single turn. They are available with or without a silicone O-ring and in a variety of colors. Screw caps are sold separately.
