SpectraMax® i3x Multi-Mode Microplate Reader

The SpectraMax® i3x Multi-Mode Microplate Reader can perform a wide range of essential cell-based and biochemical assays using the included absorbance, fluorescence, and luminescence detection modes. SpectraMax microplate readers are the most cited and have advanced protein and cell biology research for over 40 years. 

SpectraMax i3x multi-mode microplate reader provides the flexibility to add novel detection capabilities without the need for service engineers or costly downtime it grows with you as your research areas expand. For GMP/GLP regulated labs, the readers come equipped with our industry leading SoftMax® Pro GxP Software making us your partner in compliance

Unlimited breadth of user-upgradeable application modules expands research capabilities - SpectraMax® i3x Multi-Mode Microplate Reader

The SpectraMax® i3x Multi-Mode Microplate Reader measures absorbance, fluorescence, and luminescence with available upgrades including western blot, cell imaging, and fast kinetics with injectors plus additional detection modes. With the SpectraMax® MiniMax™ 300 Imaging Cytometer, industry-leading SoftMax® Pro Software, and user-configurable detection modules, the reader provides you with the ability to explore cellular pathways and protein expression on one microplate reader. 

  • Capture flash assays with ease

    The SpectraMax i3x Injector Cartridge with SmartInject® Technology expands your research capabilities to include flash-based applications including dual luciferase and ATP assays.

  • Reduce background noise

    The cooled PMT reduces background noise allowing for a more sensitive, wide dynamic range in extremely low light.

  • Increase fluorescence performance

    Powerful combination of Xenon flash lamp and LEDs provides unmatched signal strength and superior sensitivity with Spectral Fusion™ Illumination.

Key Features of SpectraMax® i3x Multi-Mode Microplate Reader

  • User-configurable applications

    User-installable detection modules expand the reader’s detection capabilities to include AlphaScreen, time-resolved fluorescence, TR-FRET (including HTRF), fast kinetics with injectors, western blot detection, and more. 

  • No-stain cell analysis

    The StainFree™ Cell Detection Algorithm for brightfield cell segmentation enables cell counting and confluency measurement without destructive stains, simplifying the cell analysis workflow

  • Multi-channel functionality

    Two fluorescence detection channels on the MiniMax 300 cytometer enable the analysis of cell viability or cell toxicity assays, including viability assays and transfection efficiency.

  • Cellular pathway analysis

    Cell confluence and cell viability imaging, western blot analysis, and quantitation of nucleic acids and protein, can be captured on one reader. 

  • Spectral Optimization Wizard

    This built-in technology enables users to optimize their assay in a single-step by quickly identifying the best excitation and emission wavelengths. 

  • Auto Intensity Adjustment

    Our patented technology acquires data over a wide dynamic range without the need to re-read the plate due to saturation effects. PMT gain adjustment is bypassed with the use of high-power LEDs as part of the Spectral Fusion Illumination.
