Product Details
These tubes and caps have been designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene to ensure strength and clarity. The vials feature external threads that create a smooth and uniform inner surface, effectively reducing the risk of contamination. The screw caps, also constructed from polypropylene, maintain the same coefficient of expansion as the tubes, complemented by 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 design, enabling them to be easily removed or sealed with a single turn. Additionally, the caps are available with or without a silicone O-ring and come in a variety of colors, while screw caps are sold separately.
