Available with washer seal or lip seal.
Washer seal 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.
Lip seal inside the cap ensures a positive leakproof seal under even the most adverse conditions. This deep internal lip fits snugly against the interior wall of the tube preventing the contents from coming in contact with the threads, thus reducing the chances of sample contamination. Lip seal caps cannot be autoclaved since closure is made of high density polyethylene.
Flat tops provide a writing surface and can be used with automatic capping machines in packaging industries.
Attachment loop prevent contamination and mix-up.
Tubes without loop are for users who prefer to remove the caps completely from the tubes when filling or sampling.
Tamperproof screw cap with washer seal and flat top are molded with a deep internal lip that fits snugly against the interior wall of the tube. It will prevent the contents from coming in contact with the seal or threads, thereby reducing the chances of sample contamination. The cap's high profile facilitates manipulation especially in aseptic procedures. All tubes and closures are manufactured in a clean environment.
