400 Series UV/Vis Spectrophotometers

S.I. Photonics continues to dominate the field of UV/Vis spectroscopy, radiometry and color analysis 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 instruments to acquire a single wavelength. The 400 Series UV/Vis Spectrophotometers exhibit all the benefits of array detection including no moving parts, extremely high wavelength stability and reproducibility. In addition, the 400 Series UV/Vis Spectrophotometers are specifically de singed for use with fiber optic sampling accessories for unsurpassed versatility.
S.I. Photonics Model 420 UV/Vis Spectrophotometer with fiber optic dip probe sampling accessory. The 400 Series Spectrophotometers are ideally suited for demanding laboratory applications including research and QA/QC labs yet extremely rugged and virtually "student proof" for teaching laboratories as well.

Powerful yet user friendly software further add to the versatility of the
400 Series Spectrophotometers.

Model 420 UV/Vis Spectrophotometer
Intelligent and integrated software permit simultaneous acquisitions of absorbance, transmittance, reflectance and intensity measurements. Stand alone software packages are available for radiometry, emission, and color analyses including Gardner color, CIELUV, CIELAB, Hunter, yellowness index, whiteness index and tint.
