For educational purposes, the user manual includes simple experiments for the determination of max, extinction coefficient and natural bandwidth plus the construction of a standard curve and the measurement of stray light.

The Libra S4 measures Absorbance, % Transmission and concentration as well as being able to output absorbance–time plots directly to chart recorder. The instrument is delivered with Grafico PC utility software package and a serial lead, providing the student with the means to capture, print and interpret a wavelength scan from the instrument on a PC; the data for the scan or other results may be easily exported from Grafico to Excel.
