Spectrophotometry is a technique most scientists have used at some point in their careers. Whether for confirmation of a compound's identity or for quantitation of a protein, spectrophotometry in the ultraviolet and visible spectrum has rapidly found increasing applications in numerous fields within the last few years. To help meet this demand, manufacturers of instrumentation for UV/Vis spectrophotometry now provide machines with a wide spectrum of features and specifications. LabConsumer contacted 16 companies and received information on over 50 UV/Vis spectrophotometers to choose from. As you will see, spectrophotometry has come a long way since Dr. Arnold Beckman constructed the original device in the 1940's.
