ABSTRACT:
A plant tissue culture vessel including a base and a mating cover wherein the base and cover include means for adjustably setting the gas exchange rate between the interior of the vessel and the ambient, and means for selectively defining a loose or tight fit between the cover and the base. The cover and base are made from a material that permits the transmission of light. A filter is provided between the mating parts of the cover and base to filter contaminants during all modes of relationship between the cover and the base. The filter is constructed from a foam urethane blank having a porosity capable of precluding the passage of dust, bacteria and virus and is formed as an endless member by being cut in strip form from a blank of material and thereafter longitudinally slit between the ends.
