AD20 Absorbance Detector, Dionex (CAT#: STEM-CPO-0378-ZJF)

The manufacturer of the AD20 Absorbance Detector, Dionex is Dionex.
Refurbished Dionex AD20 Absorbance Detector (AD 20). (p/n AD20-1) The Dionex AD20 Absorbance Detector is a dual-beam, variable wavelength photometer. Full spectral capability is provided by two light sources: a deuterium lamp for ultraviolet detection and a tungsten lamp for visible wavelength operation. The Dionex AD20 features programmable wavelength selection and automatic calibration for precision, reproducibility, and ease-of-use. May be available as part of the Dionex DX-500 system and as a stand-alone unit.
