Abstract

A tissue culture cluster dish, having a lid which may be removably placed on a base having formed in it a plurality of wells for the placement and growth of tissue cultures; the wells having well bottoms which are transparent and flat for easy viewing of the well contents, the well bottoms being elevated above the plane in which the base makes contact with any horizontal planar surface upon which the base is placed; the base having ribbing which extends below and surrounds the well bottoms, the base further having a base rim of sufficient vertical extend for easy grasping and holding; the lid coming in contact with and being supported by the base only through protrusions upwardly extending from the base, thereby assuring atmospheric communication between the well interiors and the outside of the dish; the lid having ridges to prevent transfer of moisture from the area above one well to that above any other well; and the lid fitting on the base only in one orientation.

Dependent claims

A tissue culture cluster dish assembly comprising:

a base having formed within it a plurality of wells for receiving materials,
said wells formed in said base having flat bottoms for distortion free viewing, by a user, of the material received, and undergoing change, in said wells,
said base having a front end and a back end;
a lid for covering said base and the wells therein,
said lid having a front end and back end,
said lid being removably locatable on said base,
said lid and said base being formed of a transparent material,
said base having a base rim running around said base,
said base rim having a lower edge which constitutes the lowest extremity of said base and which lies in a plane so that said base may be supported thereon when placed upon a planar surface,
said flat bottoms of said wells lying in a plane elevated above and parallel to the plane in which said lower edge of said base rim lies so that said well bottoms cannot be scratched or soiled by making contact with any planar horizontal surface upon which said base may be placed,
said wells formed in said base each having vertical well walls,
said well walls each having upper edges which constitute the upper extremities of said base and which all lie in the same plane which is parallel to that in which said lower edge of said base rim lies,
said well walls having, at their bottoms, ribs extending downwardly below the plane in which said well bottoms lie,
said ribs running around the peripheries of said well bottoms thereby reducing the likelihood of the scratching and soiling of the lower surfaces of said well bottoms when said tissue culture cluster dish is being handled.
