ABSTRACT:
The sample rack for holding sample tubes includes a front shell and a rear shell co-joined together in clam shell arrangement. The rack includes tube receiving chambers, each of which has a tube engagement cradle that is arranged to engage a surface portion of a sample tube inserted in the tube receiving chamber. Portions of the tube engagement cradle are formed on each of the front and rear shells and the co-joining of the shells completes the structure of the tube engagement cradle. Each tube receiving chamber also includes a depending biasing spring leg that urges the sample tube toward the tube engagement cradle. The rack also includes spring mount portions for supporting biasing springs that incorporate the biasing spring legs. Segments of the spring mount portion are also formed on each of the front and rear shells and the co-joining of the shells completes the structure of the spring mount portion.
