With the option to be configured with up to 4 lasers and 14 colors for multi-parameter analysis the Attune NxT Acoustic Focusing Cytometer was designed as a modular system to fit most experimental needs and lab budgets. The novel design of the optical path helps ensure precise fixed alignment of four spatially separated lasers onto the sample stream enabling consistency in data over time, superior performance, and superior reliability. The instrument can be configured with up to 4 solid-state lasers (405 nm, 488 nm, 561 nm, and 637 nm) with flat top beam profiles.
The Attune NxT Flow Cytometer's acoustic focusing uses ultrasonic radiation pressure (>
2 MHz) to transport particles into the center of the sample stream. This pre-focused stream is then injected into the sheath stream, which supplies an additional hydrodynamic pressure to the sample. The combination of these two forces- termed acoustic-assisted hydrodynamic focusing-results in a narrow core stream and uniform laser illumination, regardless of the sample input rate. In traditional cytometers that rely solely on hydrodynamic focusing, the sample core widens to accommodate the increases in flow rate, which results in less uniform laser light illumination.
