Save time—10X faster speed with no loss in data quality

The Attune NxT flow cytometer, designed using acoustic-assisted hydrodynamic focusing, achieves sample-throughput rates of of 12.5 µL/min–1 mL/min or 12.5–1,000 µL/min—up to 10 times faster than traditional hydrodynamic focusing systems and data acquisition speeds of 35,000 events/sec.

bar graph comparing speed of Attune NxT Cytometer to competitor instruments

The Attune NxT Flow Cytometer acquires 1,000,000 events in a fraction of the time required compared to three competitor instruments.  Data represents protocol time achieved by running the flow cytometers at maximum sample rates for each instrument (1,000 µL/min for the Attune NxT Cytometer).

Minimal data variation at high sample rates with the Attune NxT Flow Cytometer. Jurkat cells were fixed and stained with propidium iodide, treated with RNase and analyzed at a concentration of 1 x 106 cells/mL on the Attune NxT Flow Cytometer. Regardless of sample rate, the coefficient of variation (CV) of cells in the G0/G1 and G2/M phases remain consistent, even at the highest sample rate of 1,000 μL/min.


Simplified sample prep—no wash, no lyse options

Acoustic focusing allows significantly higher sample rates, which simplifies sample preparation, reduces protocol times, and minimizes cell loss. This feature is useful for no wash, no lyse immunophenotyping protocols using whole blood and for samples that are inherently low in concentration, including cerebrospinal fluid and stem cell preparations.
