The Unico Double Beam Spectrophotometer SQ-4802 is a Double-beam design. It is a stand-alone model with a 1.8 nm fixed bandwidth and has all the features that the SpectroQuest line offers in a stand-alone unit. The two detectors are measuring sample and reference respectively and simultaneously for optimizing measurement accuracy. It provides excellent performance for measurements in the range of 190nm to 1100nm. It is suitable for pharmaceutical, biochemical and clinical lab applications as well as routine applications such as quantitative analyses, kinetics, spectrum scanning, multiple components and DNA/Protein.
Optional software makes this instrument versatile.
