1. A linear wash system configured for use in an immunoanalyzer, comprising:
a first temperature-controlled cuvette incubation ring that has a plurality circumferential slots each configured to hold one of a plurality of sample cuvettes;
a linear track placed inside and coplanar to the first temperature-controlled cuvette incubation ring and configured to transport the plurality of sample cuvettes;
a motorized belt configured to engage the plurality of sample cuvettes and provide motive force along the linear track; and
one or more wash stations along the linear track,
each wash station comprising
one or more magnets configured to provide a magnetic field on plurality of sample cuvettes and
a pipette configured to rinse the contents of each sample cuvette while in the magnetic field of the one or more magnets,
wherein the linear track terminates in an input end configured to receive each sample cuvette from a first circumferential slot of the first cuvette incubation ring and terminates in an output end configured to deliver each sample cuvette to a second circumferential slot in the first temperature-controlled cuvette incubation.
