The Thermo Scientific™ Varioskan™ LUX Multimode Microplate Reader is an advanced, flexible instrument designed to meet the diverse needs of life science laboratories. It supports multiple detection modes including absorbance (200–1000 nm), fluorescence intensity (including FRET), luminescence (including BRET), time-resolved fluorescence (TRF and TR-FRET), and Alpha technologies such as AlphaScreen and AlphaLISA making it suitable for a wide range of applications such as cell-based assays, enzyme kinetics, and molecular interaction studies. The Varioskan LUX features automatic dynamic range selection, which optimizes signal detection per well without manual adjustment, increasing both speed and reliability. Its modular design ensures easy upgrades and customization, while intelligent safety checks help prevent user errors during setup or operation. Controlled by Thermo Scientific’s intuitive SkanIt™ software, the system enables streamlined data acquisition and analysis, making complex assays simple to perform. The instrument is validated for high-performance assays like HTRF and Dual-Luciferase® Reporter assays, and its automation-ready design allows seamless integration with robotic systems. With fast reading speeds, high sensitivity, and robust performance, the Varioskan LUX is an ideal solution for researchers seeking precision and efficiency in microplate-based detection.
