Abstract
Medical testing apparatus including a microprocessor controlled centrifuge having a group of cuvettes therein. The apparatus also includes a microdiluter apparatus with a pair of pumps therein of differing diluting capability. The cuvettes have hollow main bodies produced from transparent material to allow analysis of the specimen within the cuvettes by a series of spectrophotometers adapted to read the cuvettes while they are rotating within the centrifuge. Bags of reagent are received within the cuvettes and are designed to burst upon reaching a given level of centrifugal force allowing the reagent to flow from the bags into a test chamber within the cuvette main body. Projections are provided on the cuvettes to control the orientation of the cuvettes when inserted into the microdiluter apparatus. A tab is provided on each cuvette in proper orientation to actuate the appropriate microdiluter pump for the test the cuvette is intended for. The cuvette projections also are coded with a binary code to produce a signal which indicates to the test apparatus which test is being carried out in the cuvette. The apparatus also includes means for receiving the signal from the code reader an…
