Abstract
A cover is provided for a Petri dish including a base portion having a continuous peripheral sidewall for holding a layer of a gel medium having a predetermined depth for growing micro-organisms. The cover comprises a top portion having an inner surface, and a depending integral peripheral flange for receiving the sidewall of the base portion in a closed position. A plurality of posts depend orthogonally from the inner surface of the top portion to free distal ends. The posts are sufficiently long such that the free distal ends of the posts extend into the liquid gel medium when the cover is in the closed position. The posts cause an array of wells to form in the surface of the hardened gel medium corresponding to the depth of penetration of the posts into the medium.
