Six styles of caps to choose from and two sealing types: O-ring seal and lip seal
The cap is molded with a deep internal lip that fits snugly against the interior wall of the tube thus preventing 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 and can remain attached (T332 & T336 Series) to the tube in order to eliminate mix-ups and contamination. All tubes and closures are manufactured in a clean environment.
The following closures have a flat top to accommodate automatic capping machines in packaging industries.
Certified RNase-, DNase-, Pyrogen- and DNA-free.
