Tubes/Vials/Cuvettes

Made of polypropylene. The O-Ring secured in the top of the cap ensures a positive leakproof seal, time after time, keeping the integrity of small samples under even the most adverse conditions. The caps do not have the attachment loops for users who prefer to remove the caps completely from the tubes when filling or sampling. Perfect for cryogenic work. Non Skirted tube can be centrifuged. Can be centrifuged up to 17,000g. Will withstand temperatures from -196°C to +121°C.

Caps with a silicone washer between the cap and the tube to ensure a positive leakproof seal at all temperatures. As for tubes, these closures are also made of polypropylene, providing the same coefficient of expansion for both, which further enhances the leakproof qualities of the vials at changing temperatures. The cap features a long skirt and a super-fast thread design that allows it to be removed or sealed with a single turn.
