A cassette for containment, storage and processing of material samples, having a top member that is slideably attachable to and detachable from the base member with minimal force and relaxed requirement for precision in the alignment operation. The top member is hingeably connected to the base member when attached and is positively locked to the base member in the attached closed position. The top member is easily opened and closed with one hand when attached to the base member, and facilitates high volume sample processing, e.g., of tissue samples for the purpose of histological determinations.

1. A cassette having utility for holding a material sample, said cassette comprising: a base member comprising a liquid-permeable bottom surface and a plurality of wall members defining a sample chamber for holding the sample therein, said wall members including side walls, and each of said side walls having a top edge and an inside surface; a top member adapted to be supported on the base member and latched thereto, covering the sample chamber to retain said sample in the sample chamber when in a closed position, and a pair of protrusions extending outwardly from opposite edges of the top member, wherein the top member is slideably attachable to and detachable from the base member through a hinge mechanism at said hinged attachment, without deformation of or damage to the hinge mechanism, so that when said top member is attached to and positively locked to the base member at the point of hinged attachment, said top member and said base member are hingedly coupled to each other, wherein said hinge mechanism includes guide channels leading from the top edge of the inside surface of the side walls, and said guide channels receive said pair of protrusions; and the top member comprises a plurality of latching means at points distant to the point of hinged attachment, whereby said plurality of latching means affix the top member to the base member when in the closed position, so that the top member covers the sample chamber of the base member.
