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