The TriStar² S is a fully modular Multi-Mode Microplate reader with both Monochromator and Filters offering  Luminescence and BRET, Fluorescence and FRET, TRF and UV/Vis absorbance measurements. It is a perfect fit for Life Sciences research and has been developed to support a fully modular approach.With TriStar² S the successful multi-technology microplate reader platform has been extended in its modularity, performance and user-friendliness by adding additional reading technologies and a double monochromator for wavelength selection in absorbance and fluorescence excitation.The TriStar² S is a fully modular microplate reader. Any combination of reading technologies and options can be composed maintaining all possibilities of later upgrades.The optical system ONE-4-ALL with a new revolutionary design is the first time a single optical system has been employed in a multi-technology reader that matches the performance of individual dedicated optical devices. The revolutionary 3D double monochromator offers full flexibility in wavelength selection
