1. A photometer module comprising:

  • a cover housing;

    a carriage in said housing;

    means for moving said carriage across said housing over a gel electrophoresis plate;

    a photometer supported by said carriage, said photometer comprising;

    a light source of broad wavelength spectrum to excite fluorescence;

    two photodetectors;

    a pair of filters having a first wavelength range of about 400-600 nm and a second wavelength range of about 500-700 nm, respectively, each photodetector having one of the filters in the light path to said photodetector; and

    a pair of optical fibers for receiving light and transmitting light to each of said photo detectors thorough said filters, said optical fibers transmitting and receiving fluorescent light in the range of about 400-700 nm from a gel electrophoretic narrow band, said receiving light passing through an aperture; and

    means for analyzing signals from said photodetectors to determine the wavelength range of light received by said photodetectors, whereby the wavelength range within 400-700 nm of the light received by said optical fibers is determined.
