Product Details
These tubes and caps have been designed for the storage and transportation of biological material. They are manufactured from non-toxic polypropylene, ensuring strength and clarity. The vial features external threads that create a smooth and uniform inner surface, reducing the risk of contamination. The screw caps, also made of polypropylene, exhibit the same coefficient of expansion as the tubes, complemented by a polypropylene inner lip for a leakproof seal, even under varying temperatures. The caps are designed with a long skirt and a super-fast thread mechanism, enabling removal or sealing with a single turn. Additionally, the caps are offered with or without a silicone O-ring and come in a variety of colors. Please note that screw caps are sold separately.
