Product Details
These tubes and caps have been designed for the storage and transportation of biological material, manufactured from non-toxic polypropylene to offer 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 made of polypropylene, provide the same coefficient of expansion as the tubes, along with a polypropylene inner lip, ensuring a leakproof seal even under changing temperatures. The caps are designed with a long skirt and a super-fast thread mechanism, allowing for easy removal or sealing with a single turn. Additionally, the caps are available with or without a silicone O-ring and come in a variety of colors; however, screw caps are sold separately.
