UV-Visible Spectrophotometer LBN-UV131 is a dependable and simple-to-use device with improved usability and performance. For increased longevity and flexibility, it includes automated calibration, a spill-resistant sample compartment, and a small foot print. The single beam instrument has high precision within the wavelength range of 200-1000 nm and an adjustable bandwidth of 4 nm, making it ideal for samples with sharp absorption peaks. The switching of tungsten and deuterium lamps is automatic within a selectable wavelength range, and the device includes a four-position cell holder with 10 mm pathlength cuvettes.
