The Model 430 Visible Spectrophotometer
Model 430 Visible Spectrophotometer with a Universal Optics Bench Sampling Accessory
The 400 Series Spectrophotometers have become the industry leader for high performance UV-Vis spectroscopy. Analytical performance and long term stability closely matches those of double beam instruments costing twice as much. The Model 430 is based on our popular Model 440 platform but only contains a tungsten lamp for the visible wavelength range between 350 nm and 980 nm.
The Model 430 incorporates high sensitivity, low drift making it ideal for low light applications including fluorescence and reflectance measurements.
