UV-Vis Spectroscopy

The double beam Agilent (Varian) Cary 5000 UV–Vis-NIR spectrophotometer is powerful to perform transmittance or absorptance and reflectance (diffuse, specular, fixed angle) measurements on solid and liquid samples, in the 175-2500 nm spectral range . The advantage of a double beam instrument is the automatic compensation of instrumental variations, like the override of lamp effects due to random fluctuations or  temperature.

Controlled by the Cary WinUV software, a modular Windows-based software, makes it easy to perform powerful analysis and control a number of optional accessories. The large sample compartment can be expanded to hold large accessories and integrating spheres for spectral and diffuse reflectance. The LockDown mechanism makes it possible to quickly change and position accessories for reproducible results.

It is equipped with Variable slit widths (down to 0.01 nm) for optimum control over data resolution
