Product Details
These tubes and caps are specifically 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 the risk of contamination. Each vial is complemented by screw caps made from the same polypropylene material, which maintains an identical coefficient of expansion. This combination, along with a polypropylene inner lip, guarantees a leakproof seal even under varying temperatures. The screw caps have a long skirt and a super-fast thread design that facilitates easy removal or sealing with just a single turn. Caps are available with or without a silicone O-ring and come in a variety of colors, although it is important to note that the screw caps are sold separately.
