Description

Spectrophotometer, UV-Vis, Varian Cary 50 bio, Refurbished

The Varian Cary 50 Bio UV-Visible Spectrophotometer with Cary 16 Channel-MPM Code 1003-0203, has a data collection rate of 80 points per sec; a max scan rate is 24,000 nm per minute; Wavelength range of 190-1100 nm is scanable in less than 3 seconds; and measure samples up to 3 Abs. Excellent noise performance is achieved with the highly focussed and very intense light beam, even when using small aperture microcells. The Varian Cary 50’s super-concentrated beam makes it ideal for fibre optic work, offering excellent coupling efficiency and light throughput. Its room-light immunity makes shielding of a fibre optic probe unnecessary.
