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. The vials feature external threads, providing a smooth and uniform inner surface that reduces the risk of contamination. The screw caps are also made of polypropylene, ensuring the same coefficient of expansion as the tubes, which, along with a polypropylene inner lip, guarantees a leakproof seal even at varying temperatures. The caps include a long skirt and a super-fast thread design, enabling removal or sealing with a single turn. Optional silicone O-rings are available with the caps, which can be customized in a variety of colors. Screw caps are sold separately.
