Varian Cary 50 Bio UV-VIS Spectrophotometer

Excellent noise performance is achieved due to the highly focused and intense light beam, even when using small aperture microcells.

The Varian Cary 50's super-focused beam makes it ideal for fiber optic work, offering excellent coupling efficiency and high light throughput. Its immunity to ambient light makes it unnecessary to shield a fiber optic probe.
