An analyzer for performing automated assay testing. The analyzer includes a storage and conveyor system for conveying cuvettes to an incubation or processing conveyor, a storage and selection system for test sample containers, a storage and selection system for reagent containers, sample and reagent aspirating and dispensing probes, a separation system for separating bound from unbound tracer or labeled reagent, a detection system and date collection/processing system. All of the sub-units of the machine are controlled by a central processing unit to coordinate the activity of all of the subunits of the analyzer. The analyzer is specifically suited for performing heterogeneous binding assay protocols, particularly immunoassays.

A module for providing a constant luminescence source for monitoring a chemiluminescence assay apparatus, said module comprising: (a) a constant, temperature-compensated reference voltage source grounded through a reference resistance to produce a constant, reference current source, (b) a current driven light source having a target output value, (c) a photodiode to which the light source is coupled, and (d) a differential amplifying means connected to the constant, reference current source and the photodiode and configured to present its output to the light source so as to reduce the current through the light source when the light source output is above the target value and to increase the current when the light source output is below the target value.
