ABSTRACT:
A method of and apparatus for automatically taking monochromatic light absorbance measurements on a plurality of fluid samples such as serum. The fluid samples to be processed are contained in a vessel having a plurality of cuvettes into each of which is disposed a fluid sample to be analyzed and which vessel is on a processing path and moved by a unique drive belt mechanism capable of providing a plurality of movements to the vessel in different directions and selectively to a first position or station whereat the cuvettes in said vessel are washed and evacuated of any unbound materials and then to a second station whereat a reagent is sequentially and serially added to each of the cuvettes, after which the fluid sample in each cuvette is exposed to a monochromatic light absorbance measuring device straddling the track at said second position and a spectroanalysis is made thereof. The drive belt is actuated by a synchronous motor programmed to selectively position the cuvettes in predetermined, timed sequence--first at the wash and evacuate station and then at the reagent additive and analysis second station. The apparatus in coaction with the motor may be automatic and/or manually operable whereby a very large number of fluid samples may be very quickly analyzed for mass testing of large populations for highly infectious diseases.
