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 feature external threads that provide a smooth and uniform inner surface, which reduces the risk of contamination. The screw caps, made of polypropylene, share the same coefficient of expansion as the tubes, ensuring a leakproof seal even under varying temperatures. The caps come with a long skirt and a super-fast thread design, allowing for easy removal or sealing with a single turn. Available options include caps with or without a silicone O-ring and a variety of color choices. The screw caps are sold separately.
