Spectrophotometer
Spectrophotometer
- Description
- Arnold O. Beckman, a professor of chemistry at the California Institute of Technology, established National Technical Laboratories in Pasadena, Ca., in 1935. That firm introduced the DU spectrophotometer in 1941. Using quartz rather than ordinary glass, this instrument extended observations into the near ultra-violet. The form remained on the market until 1976, with thousands of examples sold.
- This early example came from Beckman Instruments. The inscription on an oval tag reads “BECKMAN / MODEL DU SERIAL 2960 QUARTZ SPECTROPHOTOMETER / NATIONAL TECHNICAL LABORATORIES SOUTH PASADENA, CALIFORNIA, U.S.A.”
