The Thermo Scientific™ Varioskan™ LUX Multimode Microplate Reader (VLBL0TD1) delivers unmatched flexibility, precision, and automation for multimode microplate-based assays, integrating Absorbance (UV-Vis), Fluorescence Intensity, Luminescence, and Time-Resolved Fluorescence (TRF) technologies.
Equipped with a single integrated dispenser for accurate reagent addition, this configuration is ideal for enzyme kinetics, luminescent reactions, and time-critical fluorescence assays. Its dual top and bottom reading optics enable maximum assay adaptability for both homogeneous and adherent cell-based applications.
Validated for HTRF™ (Cisbio) and DLReady™ (Promega) assays, the Varioskan LUX combines advanced automation, dynamic range optimization, and SkanIt™ Software integration to simplify workflows, ensure reproducibility, and support high-throughput research environments.
