SECTION 1 - Introduction
1.1 INSTRUMENT DESCRIPTION
The 7310 and 7315 spectrophotometers are suited to a wide range of applications in education,
quality control, environmental and clinical analysis. The 7310 is a visible spectrophotometer covering
a wavelength range from 320nm to 1000nm. The 7315 is a UV/Visible spectrophotometer with a
wavelength range from 198nm to 1000nm. Both models have five measurement modes: photometrics,
concentration, spectrum scanning, quantitation and kinetics. These instruments use icon driven software
and have an improved navigation system for easy and intuitive usability.
