1265 - Bausch & Spectronic 20

Listing description

The Bausch and Lomb Spectronic 20 spectrophotometer is a line-operated single-beam instrument. Radiation from the source (a tungsten filament lamp) is dispersed by a replica grating, and the desired wavelength is focused upon an exit slit. The emergent beam passes through the cell compartment; that portion which is not absorbed is measured by a phototube. The response of the phototube is recorded in terms of transmittance (upper scale) or of absorbance (lower scale).
Description:

The Bausch & Lomb Spectronic 20 is ideal for a wide range of research and classroom applications. It is rugged enough for classroom use and reliable for industrial or research applications. Single-beam unit is suitable for general colorimetric and spectrophotometric applications. Easy-to-use, reliable, and efficient. Sample compartment holds a wide range of cuvettes, adapters, and test tubes for a diverse range of chemical tests. Unit accepts sample volumes as low as 0.75mL. Wavelength range: 340-640, or 400-700 or 650-950, depending on phototube and filer installed. Spectral Slitwidth 20nm
