摘要： A cassette for supporting a plurality of cylindrically-shaped containers (e.g., test tubes) of randomly varying diameters in spaced parallel relationship includes a frame supporting a plurality of tube centering assemblies in side-by-side relationship. Each tube-centering assembly comprises a housing defining a through opening for receiving a container, and a pair of cooperating collar members slidably mounted on the housing for movement towards and away from each other. Each of the collar members has an arcuate surface adapted to contact a side wall of a received container during the sliding movement thereof. A spring is provided to bias the collar members towards each other and towards engagement with the side wall of a received container, whereby the collar members cooperate in supporting a received container therebetween.
