1.1 inStRUMent DeSCRiPtion
The 7300 and 7305 spectrophotometers are suited to a wide range of applications in education,
quality control, environmental and clinical analysis. The 7300 is a visible spectrophotometer covering
a wavelength range from 320nm to 1000nm. The 7305 is a UV/Visible spectrophotometer with a
wavelength range from 198nm to 1000nm. Both models feature measurement modes for absorbance,
% transmittance and concentration. These instruments use icon driven software and have an improved
navigation system for easy and intuitive usability.
