UV-Visible Spectrophotometer LBN-UV133 is a double beam instrument with a computer simulation optimized optical base. The continuously adjustable spectral bandwidth ranges from 0.1 to 5nm, making it ideal for samples with sharp absorption peaks. Precision is improved across the UV-Vis spectrum, from 190nm to 900nm, due to the well-aligned PMT detector and high-quality deuterium, tungsten, and mercury lamps. The device includes an optional 8-position cell holder as well as a high throughput 100-position autosampler with an easy-to-use interface.
