Product Details
These tubes and caps have been 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 provide a smooth and uniform inner surface, minimizing the risk of contamination. The screw caps, also made of polypropylene, maintain the same coefficient of expansion as the tubes; this, combined with a polypropylene inner lip, guarantees a leakproof seal even under varying temperatures. The caps are designed with a long skirt and a super-fast thread design 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, with screw caps sold separately.
