VersaMax ELISA Microplate Reader

A powerful, affordable catalyst for scientific accomplishment

Make the most of your budget with the VersaMax™ ELISA Microplate Reader, our affordable, visible spectrum absorbance reader for 96-well microplates. This richly featured reader gives you the speed, convenience, and economy of monochromator-based wavelength selection for visible absorbance measurements between 340 nm and 850 nm, so you can accomplish more, with less.

  • Eliminate the need for purchasing and changing out filters for wavelength optimization with a monochromator-based wavelength selection for visible absorbance between 340 nm and 850 nm
  • Read up to 2 wavelengths in endpoint or kinetic mode for 96-well plates
  • Report results with confidence: Patented multichannel optical design mimics a dual-beam spectrophotometer, measures each sample in the plate directly, and eliminates error due to variations in light output between optical fibers on other instruments
  • Monitor temperature-sensitive reactions with consistent temperature regulation from ambient to 45°C
  • Correct for varying microplate well volumes and eliminate standard curves using PathCheck® Technology, the only temperature-independent pathlength correction method
  • Mix samples thoroughly in microplate wells with user-programmable Automix feature
  • Analyze data using SoftMax® Pro Software comprehensive data analysis software
  • Automate seamlessly with the StakMax® Microplate Handling Stacker
