Abstract
A device for colorimetric analysis of samples comprises a plurality of groups of receptacles, means for bringing these groups successively to a testing station, and means for automatically performing a cycle of analysis on the receptacles of the group at that station. The analysis means includes a light source, a photodetector aligned therewith, and a plurality of filters. The receptacles of each group and respective filters are moved successively into alignment with the source and detector so that the contents of each receptacle are analyzed with the aid of the correct corresponding filter.
