Product Details
These tubes and caps have been designed for the storage and transportation of biological material. They are manufactured from non-toxic polypropylene, which offers strength and clarity. The vial features external threads that provide a smooth and uniform inner surface, reducing the risk of contamination. The screw caps, made of polypropylene, maintain the same coefficient of expansion as the tubes, ensuring a leakproof seal even at varying temperatures, thanks to a polypropylene inner lip. The caps come with a long skirt and a super-fast thread design, allowing for easy removal or sealing with a single turn. They are available with or without a silicone O-ring and in a variety of colors, with screw caps sold separately.
