Product Details
These tubes and caps have been designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene to provide strength and clarity. The vial features external threads that create a smooth and uniform inner surface, reducing the risk of contamination. The screw caps, also constructed from polypropylene, match the tubes' coefficient of expansion, and include a polypropylene inner lip to ensure a leakproof seal even under varying temperatures. The caps are designed with a long skirt and a super-fast thread, enabling easy removal or sealing with a single turn. Additionally, the caps are available with or without a silicone O-ring and come in various colors, with screw caps sold separately.
