Abstract
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.
