Product Details
These tubes and caps are 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, minimizing contamination risks. The polypropylene screw caps match the tubes' coefficient of expansion, and the addition of a polypropylene inner lip guarantees a leakproof seal even with temperature fluctuations. The caps are designed with a long skirt and a super-fast thread, facilitating easy removal or sealing with a single turn. They are available with or without a silicone O-ring and come in various colors, with screw caps sold separately.
