A well plate assembly useful for laboratory-scale cell culture and diagnostic tests of the present invention includes a substantially planar base with at least one well and a top surface. A lid is joined to the base by a hinge as part of the assembly. The hinge allows the lid to be moved between a closed position, where the lid covers the top surface, and a plurality of open positions where the top surface is uncovered. The assembly includes provisions for releasably retaining the lid in the closed and plurality of open positions.

Plate assembly useful for microbiological laboratory procedures

This invention involves racks or tray arrays for use in clinical laboratories, in particular, to support tubes and other containers holding body fluid specimens. The invention allows the user to 'build' racks or arrays of larger and/or smaller capacity, depending upon the user's requirements, by rapid snapping together of a plurality of identical modular tube units. The racks or units may have a variety of size openings for accommodating different size specimen containers, and containers of different configuration. Thus, the user can maintain stable support of a great many containers simultaneously for handling in the laboratory, thus avoiding the danger of dropping or spilling specimens. The arrangements of the invention may be comprised of reusable, autoclavable moldable plastic materials, or less expensive throw away moldable materials. The individual components making up the tube rack array may be of a variety of geometric configurations.
