UNICO SQ-4802 is a Double beam design. It is a stand-alone
model with 1.8 nm fixed bandwidth and has all the features that 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
