A multibeam photometric measuring device includes a single light source along with a filter assembly for passing only a desired band of wavelengths and an optical system for suitably focusing light from the light source. Light is transmitted individually to each of a plurality of sites disposed on a multi-well sample plate. Enhancement of color distribution is provided by automatic agitation of the reacting agents within the sample wells before a reading is taken at each of the sampling intervals of a kinetic measurement sequence.

A multibeam photometric measurement device for measuring optical density of samples contained in a plurality of sample sites disposed on a multi-site assay plate, said device comprising: a single light source adapted through coupling means to be selectively applied, according to a predetermined sequence, through selected ones of a plurality of light transmitting means to selected ones of said samples sites: a plurality of photodetector means disposed on a detector board and positioned in relation to said assay plate in such a way that light transmitted through each of said sites is received by a corresponding photodetector; means for simultaneously imparting mixing movement to said samples comprising means for imparting movement to said assay plate for a predetermined time before a reading is performed on a sample site; and means for analyzing the output of said photodetector means to determine and indicate the optical density of said sites.
