Multimode Microplate Reader Varioskan™ LUX

Varioskan™ LUX was developed for users with varied requirements. It offers different functions which help to save time and avoid mistakes in the laboratory. One of them is the automatic dynamic range selection, which adjusts the optimal reading range based on signal intensities, as well as intelligent self-diagnostics systems, which recognise possible errors and warn the user in order to avoid affecting the results.
Varioskan™ LUX is a modular, upgradable system for customisation of research needs:
  • Up to 5 measurement technologies: absorbance (UV-Vis, incl. pathlength correction), fluorescence intensity (incl. FRET), luminescence (direct and filtered, incl. BRET), AlphaScreen / AlphaLISA, time-resolved fluorescence (incl. TR-FRET, hTRF).
  • Depending on the measurement technology, Varioskan™ LUX selects the optimal wavelength using filters or monochromators.
  • Spectral scanning for assay optimisation.
  • Five measurement modes: end-point, kinetic, spectra, multipoint and kinetic spectra.
  • Integrated gas module for atmospheric control of CO2 and O2 for cell-based assays.
  • Simultaneous dispensing and measurement for follow-up of fast reactions right from the reaction start.
  • Automatic dynamic range selects optimal reading range based on signal intensity.
  • Smart safety controls help protect instrument and samples from user error.
  • Autocalibration and self-diagnostics for confidence in results.
  • Can be equipped with up to 2 onboard dispensers, allowing for easy and accurate reagent addition.

Paired with Thermo Scientific™ SkanIt™ software for intuitive instrument control and easy data handling:
  • No limit on the number of licenses; install the software on as many computers as needed.
  • Intuitive user-interface simplifies measurement setup.
  • Virtual pipette™ tool makes it easy to define samples to plate layout.
  • Measurement data continuously saved to the database; helps to prevent data loss due to interruptions such as power outage or accidental aborting.
  • Manual or automatic data export to any location.
  • Several file formats for data export: *.xlsx, *.pdf, *.xml and *.txt.
  • Measurement technologies: absorbance and fluorescence intensity as standard, optional time-resolved fluorescence, luminescence, AlphaScreen.
  • Further options: up to 2 dispensers, integrated gas module.
