Model 440 UV/Visible Spectrophotometer
S.I. Photonics continues to dominate UV-Vis spectroscopy with the revolutionary design of the 400 Series UV-Vis Spectrophotometers. High sensitivity, low noise charge coupled device (CCD) detectors provide the ability to acquire a full spectrum in the time it takes scanning UV-Vis spectrophotometers to acquire a single wavelength.
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.
