The CytoFLEX S system provides powerful sensitivity and resolution from the most simple to the most demanding flow cytometry research applications. It offers easily upgradeable detection capabilities with configurations ranging from 2 laser (e.g. Blue & Yellow) and 5 colour channels up to 4 lasers (Blue, Violet with options to choose a 3rd and 4th laser as Red, Yellow, Near UV or Infrared) and 13 colour parameters in a small benchtop footprint. The CytoFLEX S matches and exceeds capabilities expected of top tier analysers, with outstanding performance and nanoparticle resolution. You can upgrade your configuration without the need for engineering intervention and with the assurance that all CytoFLEX instruments have been fully tested in their maximum configurations.
