VMax Kinetic ELISA Microplate Reader

Durable, filter-based absorbance microplate reader with additional kinetic assay measurement functionality for 96-well plate formats

The first of its kind for monitoring reactions over time—VMax® Kinetic ELISA Microplate Reader opened the door to enzyme assays and continues to be the workhorse of the laboratory environment.


  • Extend uptime with an estimated 20,000 hour mean time between failure
  • Maximize assay signal-to-noise ratios through a unique optical system that directs all available light to each well
  • Achieve higher throughput with a 5-second microplate read time
  • Easy to use SoftMax® Pro Software


  • Read up to 2 wavelengths in endpoint or kinetic absorbance for 96-well plates
  • Mix samples in microplate wells by user-programmable Automix feature
  • Operate without an attached computer using the onboard microprocessor
  • Add assay flexibility with additional filters
