The document summarizes the features and capabilities of the Beckman Coulter DU 700 Series Spectrophotometer. It can measure wavelengths from 190-1100 nm with a spectral bandwidth of 3.0 nm. The spectrophotometer has interchangeable cell holders and modules, a touch screen user interface, and stores up to 50 methods. It also has features such as automatic lamp turn-off, USB connectivity, and software for single component analysis, protein assays, nucleic acid analysis and more. System checks can be run to validate performance metrics like wavelength accuracy, photometric accuracy, and stray light levels.
