Beckman Coulter CytoFLEX nano Flow Cytometer
Item#: CYTOFLEX-Nano FlowSpecifically designed for the analysis of nanoparticles, the CytoFLEX nano Flow Cytometer overcomes the limitations of traditional flow cytometry, giving researchers a sensitive, consistent and flexible solution that can help them advance their research.
The CytoFLEX nano Flow Cytometer is a pivotal development in flow cytometry that allows users to analyze extracellular vesicles (EVs) at least as small as 40 nm* with ease while simultaneously offering up to 6 separate fluorescent channels of detection and 5 side scatter channels, to deliver full characterization and open additional avenues for your nanoparticle research.
Sensitivity
With an unparalleled size sensitivity from 1µm to 40nm* and 10nm resolution,** the CytoFLEX nano flow cytometer enables the detection of smaller EV populations and their low-abundance cargo.
Flexibility
Open up your research with 6 fluorescent channels and 5 side scatter channels. Gather all the necessary data with fewer constraints.
Maximum Consistency
Maintaining contamination-free, robust instrument performance is critical when working with small size particles. Obtain reproducible results you can trust with >90% volumetric counting accuracy and <1% carryover between samples thanks to automated QC controls.
Familiarity
Built on the same principles as the CytoFLEX platform, the CytoFLEX nano flow cytometer features a similar footprint and user-friendly software interface.
Size
Particle size determination by flow cytometry requires calibration using an appropriately characterized reference particle paired with a calibration method. Latex polystyrene particles are the tool of choice for this task due to their NIST-traceable nature and reliably consistent manufacturing. Through the calibration method taught to each CytoFLEX nano flow cytometer customer, data will be reliably reportable in absolute units for method comparison and correlation.
Count
The most robust counting methods rely on highly controlled volumetric delivery of samples rather than hand loading samples with the implied variability. The CytoFLEX nano flow cytometer allows users to customize their sample handling so that the right amount of sample is used for the results needed.
Characterize
The ability to describe nanoscale particles requires best-in-class sensitivity. To make this possible, the CytoFLEX nano flow cytometer has completely redesigned the optics and fluidics system to maximize the detection of even the smallest amounts of fluorescence across 6 detection channels and excited by 4 collinear lasers.
