Beckman DU Spectrophotometer

Description
The Beckman DU spectrophotometer is perhaps the greatest single instrument of the postwar period. The original design dates from 1941, but the machine really became "the universal spectrophotometer" in the science boom after World War II. More accurate than the Universal or the Spectronic 20, it produces accurate absorption spectra in both the ultraviolet and the visible regions of the spectrum with relative ease and repeatable accuracy. Although attempts were made to automate its scan and add recording features, it remained a point-by-point instrument that, although no longer made, still finds applications in today's laboratory.
The instrument is housed in a black steel case with a wrinkle finish.
