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 curvettes 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 thence 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 thence 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.
