Abstract

A specimen tray assembly for use in an automatic analyzing system for analyzing a plurality of specimen within the tray. The assembly includes a container tray having a plurality of microcuvettes arranged in a spaced apart grid-like pattern. A cover member is adapted to seat over the top surface of the container tray, the cover member including a system for automatically centering the container tray relative to the cover member to provide proper seating of the cover member on the container tray.

Claims

1. A specimen tray assembly, said assembly being adopted to contain a plurality of separate specimens for analysis, said assembly comprising:

a container tray having a plurality of microcuvettes having a desired diameter and being arranged in a spaced apart grid-like pattern;

a cover member seated over a top surface of said container tray, said cover member includng means for automatically centering the container tray relative to the cover member to provide proper feeding of the cover member on the container tray, said cover member including tab portions extending substantially outwardly from said container tray a distance greater than said desired diameter in a plane of said cover member solely from a first and an opposing edge of said cover member, said tab portions being adapted with said tray assembly as inserted in an analyzing system to control the movement of said cover member so that the container tray can be readily removed without the cover member for analysis.

2. An assembly as in claim 1 wherein said automatic centering means comprises a recess in a bottom face of said cover member having a first peripheral wall adapted to seat about a second peripheral wall of said container tray and wherein said first peripheral wall is inclined inwardly of said periphery of said cover member whereby when said cover member is urged against a misaligned container tray, said inclined first peripheral wall acts on said container tray to center and align the container tray with respect to said cover member.

3. An assembly as in claim 2 further including stiffening means for said cover member, said stiffening means comprising a plurality of ribs along a top face of said cover member.

4. An assembly as in claim 3 wherein said container tray includes means for identifying the specimens contained in the tray.

5. An assembly as in claim 4 wherein said identifying means comprises a computer readable bar code.
