Analysis apparatus with flexible multi-analysis capability, suitable for example for biochemical constituent analysis, has a single channel of reaction vessels arranged to receive reagents from any of a battery of reagent reservoirs and has photometer elements from measuring the reaction in each reaction vessel on a repetitive sequential basis. Control elements select the sample liquid delivered to each reaction vessel, select the reagents added thereto, and select the data processing for the photometer or other measurement information secured for reactants in that reaction vessel. The photometer elements apply and detect optical energy along selected directions to provide any of several photometric measurements, including for example of colorimetry, fluorometry, or nephelometry.
