Abstract: A reagent container for use in a sample and reagent transfer system is of sector shaped configuration and has a generally vertical curved outer wall, generally vertical side walls that are disposed and angled to one another, a generally horizontal top wall with two ports through which two probes may concurrently be inserted, a generally horizontal bottom wall that has a well portion below and aligned with one port in the top wall, and a dry well channel that is open at its bottom and aligned with the other port in the top wall.

Abstract: A liquid handling system that is particularly useful in a clinical analysis system includes a cuvette loading station for receiving a centrifugal analyzer rotor with two compartment cuvettes. Fixedly mounted on transfer structure are two spaced apart liquid handling probes such that the two probes may be simultaneously inserted into the two compartments of an analysis cuvette. A sample station has a sample container support mechanism, and means for indexing the support mechanism past the sample station for sequentially positioning successive sample containers at the sample station. An auxiliary station that is spaced from the sample station a distance corresponding to the spacing of the two probes includes a support mechanism for supporting a plurality of auxiliary containers and a drive mechanism for selectively positioning auxiliary containers at the auxiliary station.
