Product Details
These tubes and caps are specifically designed for the storage and transportation of biological material. Made from non-toxic polypropylene, they offer both strength and clarity. The vials feature external threads, creating a smooth and uniform inner surface that minimizes the risk of contamination. The polypropylene screw caps match the coefficient of expansion of the tubes, and together with a polypropylene inner lip, they guarantee a leakproof seal even under fluctuating temperatures. The caps, which are available with or without a silicone O-ring, include a long skirt and a super-fast thread design, enabling easy removal or sealing with a single turn. Please note that the screw caps are sold separately.
