Product Details
These tubes and caps have been designed for the storage and transportation of biological material. They are manufactured from non-toxic polypropylene and offer strength and clarity. The vial has external threads that provide 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. This, along with a polypropylene inner lip, ensures a leakproof seal, even at changing temperatures. The caps feature a long skirt and a super-fast thread design that allows them to be removed or sealed with a single turn. Caps are available with or without a silicone O-ring and come in a variety of colors; screw caps are sold separately.
