This device allows to measure CD, LD, and absorbance simultaneously. It can measure a variety of samples, from liquids to films to solid-states. Temperature control systems can be coupled with multi-position cells to run thermal melts, providing CD and thermodynamic data sets for conformational and folding studies. Kinetic and protein dynamics studies can be performed with dedicated stopped-flow systems that can measure both CD and fluorescence. The wavelength range is ample, allowing measurements to be obtained in both the vacuum-UV and NIR spectral regions using the standard PMT detector (163 – 950 nm).
