Abstract: The clinical analyzer includes a cuvette carrier that is moved in a manner to provide flexible assay timing and variable incubation periods. Multiple assays having such varied incubation times can be run concurrently in random-access, avoiding timing conflicts. Fluid delivery stations are placed around the cuvette carrier in positions that are independent of assay timing. The cuvettes move in unison, in multiples of incremental steps, along a closed geometrical path. The cuvette carrier is movable variable distances in opposite directions in a single time cycle to position specific cuvettes at specific locations for delivery of sample or reagent. The direction of movement of the cuvette carrier is preferably based on a determination of the shortest distance between the cuvette and respective fluid delivery stations. However, in each time cycle there is a net progressive incremental stepwise movement of the cuvettes in a selected direction.

Abstract: A probe cleaning apparatus is disclosed. Probe cleaning apparatus has a body, a reservoir within the body that is configured to contain a cleaning liquid, a partition wall configured to separate the reservoir into an inner region and an outer region, one or more liquid flow paths between the inner region and an outer region, and a cleaning member arranged in the inner region that is configured to contact an outer surface of a probe when the probe is inserted into the inner region. Cleaning liquid flows through the inner region to remove residue removed by the cleaning member. In another aspect, a disposable probe cleaning apparatus is provided. Systems and methods for carrying out probe cleaning are provided, as are other aspects.
