Snap cap closure protective caps clamp firmly on tubes to help preserve sample integrity and reduce the risk of accidental infection of laboratory personnel. Caps are precision molded from low-density polyethylene, with a double-flanged seal and thumb tab that allows you to secure and remove caps easily. Two cap sizes fit most 13-mm or 16-mm glass blood-collection tubes and 12-mm plastic culture tubes. The caps are packaged in a protective poly bag within dispenser box for convenient benchtop use and storage.
