Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A clinical laboratory rack unit for joining into an array of several such units to contain a plurality of laboratory specimen containers, comprising (a) a flat bottom wall; (b) a flat top wall; (c) at least one vertical wall joining said bottom wall and said top wall; (d) at least one opening in said top wall for receiving a container in said rack unit; (e) a plurality of spaced protuberances along said vertical wall; and (f) a plurality of spaced holes along said vertical wall (g) whereby insertion of at least one of said protuberances into at least one of said holes in an adjacent rack unit provides an array of rack units for receiving laboratory specimen containers therein.
Claim 2
Dependent Claim
119 words
