Varioskan™ LUX comes equipped with a range of measurement technologies including absorbance, fluorescence intensity and FRET as standard, and with optional luminescence, AlphaScreen and time-resolved fluorescence (TRF) modules. The instrument selects the measurement wavelength using filters or monochromators, depending on which is optimal for each measurement technology.

• 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
• Accurate temperature control for temperature critical applications
• Integrated gas control module (optional) for setting CO₂ and O₂ concentrations for cell based assays
• Optional dispensers to allow simultaneous dispensing and measurement for signal monitoring at the start of a reaction

SkanIt software (available in 9 languages):
Intuitive user-interface simplifies measurement setup
Virtual pipette™ tool makes it easy to define samples to plate layout
Built-in calculation options ease data processing
Manual or automatic data export to any location
Measurement data continuously saved to the database; helps prevent data loss due to interruptions such as power outage or accidental aborting
