ABSTRACT:
A multibeam photometric measuring device includes a light assembly comprising a single modulated 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. A plurality of light transmitting means accept light and transmit it individually to each of the plurality of sites disposed on a multi-well sample plate.
Enhancement of color distribution resulting from chromogenic reactions 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.
