Claim:
Culture plate, comprising: a) a bottom element comprising a substrate including a bottom side, at least one side wall, and a top side, and at least one cavity arranged in said substrate and comprising at least one side wall surrounding said cavity, a bottom wall and an open end for receiving material to be held in the cavity and being accessible from the top side of the substrate; and b) a lid for covering the bottom element comprising a top and a peripheral side wall, wherein at least the peripheral side wall of the lid is formed at least partially of at least one filter element made of a filter material, and wherein a gas exchange between the inner volume of the culture plate and the surrounding environment is achieved via said at least one filter element; wherein the bottom side of the substrate extends above the at least one side wall of the substrate to provide an extension on which the bottom side of the at least one side wall of the lid rests against in a closed arrangement of the culture plate, and wherein the at least one side wall of the bottom element is to tapered such that the cross section of the substrate is reduced from the bottom side toward the topside of the bottom element, so that the lower edge of the at least one side wall of the lid directly contacts with a lower portion of the at least one side wall of the bottom element.
