SL 174
Fluoroscence Spectrophotometer
Ideal for use as a routine spectrofluorometer, sensitive, accurate, and flexible.
Description
ELICO's SL-174 spectrofluorometer is an instrument which takes advantage of fluorescent properties of some compounds in order to provide information regarding their concentration and chemical environment in a sample. A certain excitation wavelength is selected, and the emission is observed either at a single wavelength, or a scan is performed to record the intensity versus wavelength, also called an emission spectra.
