Flow cytometry - The CytoFLEX Platform picture

The CytoFLEX Platform

A benchtop analyzer for every application

Isolating and analyzing blood or cultured cells, bacteria, algae, yeasts, microparticles and even nanoparticles like extracellular vesicles pose no challenge for this compact but powerful cytometer in any of its 21 configurations.

The only cytometer on the market with the ability to reliably detect 80 nm polystyrene beads, the CytoFLEX is a trustworthy partner in your extracellular vesicle and other small particle research.

CytoFLEX Platform flow cytometers can accurately measure up to 21 fluorescences simultaneously, demonstrate outstanding sensitivity and reproducibility with six excitation wavelengths (355 nm, 375 nm, 405 nm, 488 nm, 638 nm and 808 nm).


Your CytoFLEX series comes fully loaded with all lasers and detectors so it's ready for your research both now and in the future. You will choose which parameters you want activated to start, and you can just unlock more later - giving you the flexibility to activate what you need, when you need it. Beckman Coulter continuously develops the CytoFLEX series, keeping in mind that existing users should be able to get their systems updated accordingly.


Each instrument includes the full complement of re-positionable band pass filters. Move filters to the activated channels based upon the wavelengths to be detected. Additional non-standard bandpass filters are available for even more assay flexibility.

High Throughput

For higher throughput applications, an optional plate loader module (96-well, standard- and deep-well plate formats) is available and for use in regulated environments the software contains tools for 21 CFR Part 11 compliance.
