Object Details
- 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 one, serial number 42175, came from the National Institutes of Health.
