Full spectral range detection for cuvettes,suitable for  96-well, and 384-well microplates.


  • No filter system: Inc384-microplate-reader_imageludes monochromator allowing up to 6 wavelengths at a time in the visible wavelength range and scanning ranges from 190-1000 nm in 1 nm increments
  • Easy assay optimization: Read a variety of sample formats from cuvettes to 96- and 384-well microplates in endpoint, kinetic, and spectral scan modes
  • Correction for varying microplate well volumes and the elimination of standard curves based on PathCheck® Technology, the only temperature-independent pathlength correction method
  • Better experimental signal discrimination using narrow absorbance bandpass for superior peak resolution and increased accuracy.
  • Monitoring of temperature-sensitive reactions with consistent temperature regulation from ambient to 45°C
  • Thorough mixing of samples in microplate wells with user-programmable Automix feature
  • Comprehensive data analysis with SoftMax® Pro Software
  • Seamless integration with the StakMax® Microplate Handling Stack

Comprehensive data analysis
With SoftMax Pro Software, choose endpoint,
kinetic, or spectral scans; view kinetic and
spectral runs in real time and collect and store
data from multiple plates, cuvettes, graphs,
analysis tables and notes sections in the same
data file. Lab processes can be automated with
the software’s interprocess messaging features and
data and template information can be exported
and imported to and from a LIMS system
