Performance Data
Why Choose Aurora?


A prodigy incorporating a unique combination of patent-pending innovative technologies that takes flow cytometry to the next level of performance and flexibility.

With three lasers, two scattering channels, and up to 48 fluorescence channels, the Aurora suits every laboratory's needs, from simple to high-complexity applications. A paradigm shifting optical design provides unprecedented flexibility, enabling the use of a wide array of new fluorochrome combinations without reconfiguring your system for each application. The optics and state-of-the-art low-noise electronics provide excellent sensitivity and resolution. Flat-Top beam profiles, combined with a uniquely designed fluidic system, translate to outstanding performance at high sample flow rates.

The end result is a system that delivers high quality data where rare and dim populations are easily resolved, regardless of assay complexity.

The new SpectroFlo® Software offers an intuitive workflow from QC to data analysis with technology-enabling tools that simplify running any application.

The Cytek team has reimagined every aspect of cytometry hardware and software to deliver an instrument that fulfills every researcher's needs.

Aurora's Revolutionary Technologies:

From Vision to Reality

The Aurora 3-laser system is capable of up to 50 detection channels (48 fluorescent channels, FSC, and violet laser SSC) and is empowered by revolutionary technologies, including:

  • Proprietary high sensitivity Coarse Wavelength Division Multiplexing (CWDM) 16-channel semiconductor detector array for each laser, enabling more efficient spectrum capture for dyes emitting in the 400-900 nm range.
  • High bandwidth electronics design scalable beyond 50 channels.
  • Robust vacuum fluidics system enables ultimate flexibility in sample input formats.
  • Exceptional small particle detection is enabled by violet laser scatter, narrow beam height, and proprietary flat top laser design.

Fluorescent Proteins and Challenging Dye Combinations

The detection of some fluorescent protein or fluorochrome combinations by conventional flow cytometry presents a challenge due to high amounts of spectral overlap (figures 1, 4). The Aurora addresses this challenge by using differences in full emission spectra signatures across all lasers to clearly resolve these combinations, even if the populations are co-expressed (figures 2, 3, 5 and 6).
