Product Details
These tubes and caps have been designed for the storage and transportation of biological material and are manufactured from non-toxic polypropylene, offering strength and clarity. The vials feature external threads that provide a smooth and uniform inner surface, reducing the risk of contamination. The polypropylene screw caps ensure compatibility with the tubes due to their identical coefficient of expansion, along with a polypropylene inner lip that guarantees a leakproof seal even under varying temperatures. The caps are designed with a long skirt and a super-fast thread, enabling them to be removed or sealed with a single turn. Additionally, the caps are available with or without a silicone O-ring and are offered in a variety of colors. Screw caps are sold separately.
