Beckman Coulter’s DU Series 700 UV/Vis scanning spectrophotometer features focused beam technology and a small bandwidth, which ensures reproducibility, even with minor variances in cell positioning. For small volumes in applications such as nucleic acid research, the instruments accommodate Beckman Coulter 50-μL Microcells. Model 720 is suited for general purpose applications and features fixed wavelength, wavelength scan, time and kinetics measurements and single component analysis. Tools for protein and nucleic acid analysis include determination of dye incorporation percentage for microarrays and a set of DNA/protein calculation and conversion tools. With a touch-screen user interface, the series is easier to use than competitive systems with keyboard controls. USB ports enable direct connections to printers and memory devices.
