The Attune™ NxT Acoustic Focusing Cytometer
A benchtop acoustic focusing cytometer
The Attune™ NxT Acoustic Focusing Cytometer is a benchtop analyzer (Figure 1) that uses acoustic focusing—a revolutionary technology that precisely aligns cells using ultrasonic waves prior to interrogation with one or more lasers. This technology enables multicolor flow cytometric analysis with significantly greater collection rates and an improved ability to detect rare events without excess sample manipulation. The Attune™ NxT system offers:
- Unique modular design—one-day field-upgradable system with configurations for 1–4 lasers and up to 14 emission channels
- Fast detection speeds—short acquisition times without loss of data quality enable applications such as rare-event detection and use of no-lyse, no-wash techniques
- Distinctive acquisition and analysis software—intuitive and powerful for users of all experience levels
- Convenient size—complete setup fits on your benchtop

Multicolor analysis in a modular design
With up to 4 lasers and 14 emission channels for multiparameter analysis, the Attune™ NxT Acoustic Focusing Cytometer was designed as a modular system to fit most experimental needs and lab budgets (Table 1). The Attune™ NxT cytometer can be configured to accommodate most common fluorophores used in flow cytometry, as well as to match the panels you are currently running. For example, with the optional violet and yellow lasers (in addition to the standard blue laser), the Attune™ NxT cytometer can be used to simultaneously detect multiple fluorescent proteins. Whether you configure your system now or upgrade later, the Attune™ NxT Acoustic Focusing Cytometer can grow with you and your research needs.
