Spectronic 20

Spectronic 20

The Spectronic 20 is a spectrophotometer developed by Bausch & Lomb in 1954. While of simple design, requiring manual setting of the wavelength and making readings from a moving-needle analog display, the unit is rugged, accurate, and easy to use. This venerable instrument is still in production use in analytic chemistry labs in both commercial and educational settings around the world.
