<p>An improved test tube rack (48) for receiving beads employed in an immunoassay is used with a matching sample tray (32), the tray and rack featuring aligning pins and holes (52, 53 and 34, 35) so that the test tubes (42) are juxtaposed with associated sample wells (32) when the rack (48) is assembled to the tray (30). The test tubes (42) are a push-fit in holes (50) in the rack (48) and are larger at their mouths than their bases; the test tubes (42) and the wells (32) interfit tightly to avoid leakage of liquid when the assembled tray and rack are inverted to deposit the beads in the test tubes. The rack and the tray are correspondingly numbered for identification of the sample wells (32) with the test tubes (42).</p> |
