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