Abstract
Cellulose stopper for test tubes and other laboratory tubes characterized in that it is formed by a preferably conical body, molded based on pressed cellulose, in which a blind axial hole is provided, which does not reach the bottom of the cap, leaving established in the base of the same, a separation zone that constitutes an air filter for the product contained in the tube or bottle, serving, in addition, said axial drill, to facilitate the extraction of the cap, with the help of a tool suitable that is introduced in the aforementioned drill.
