These 73 series single beam spectrophotometers have improved optics resulting in a narrow spectral bandwidth of 5nm and absorbance range of –0.3 to 2.5A. All models feature measurement modes for absorbance, % transmittance, and concentration. Advanced models add spectrum scanning, quantitation, and kinetics. Visible spectrum models have a tungsten halogen lamp with a "lamp save" feature which shuts off the lamp after periods of inactivity. UV/visible models feature a “press to read” xenon lamp to provide accurate readings and extend lamp life. Easily control the spectrophotometers via the RS-232 port and included software.

Icon driven software and easy to use navigation system provide intuitive usability
Autologging capabilities enable repeat measurements of the same sample with a selected time interval
Minimal footprint with large graphical display
