Talk to an Expert| Frequency | Median Droplet Size | Maximum Flow Rate |
|---|---|---|
| 48 kHz | 40 µm | 2.4 mL/s |
| 60 kHz | 31 µm | 1.2 mL/s |
| 120 kHz | 12–15 µm | 0.4 mL/s |
No lower flow limit. Wetted materials: titanium, stainless steel, PTFE. Droplet size is independent of flow rate and pressure. Sizes are measured near the nozzle tip; droplets shrink in flight, so the size at your substrate depends on standoff distance and solvent.
Key Characteristics
- Zero air, zero fluid compression — purely acoustic atomization
- Low-velocity spray (~1 m/s) for material-efficient coating
- Self-cleaning, non-clogging titanium construction
- Best with low-viscosity liquids (below 50 cP, ideally below 20 cP)
- Vacuum and pressure compatible
- Driven by 20 W broadband generator, 25–120 kHz tracking range
Measured Droplet Data — 120 kHz
| D10 (arithmetic mean) | 14.3 µm |
| D32 (Sauter mean) | 39.3 µm |
| D43 (volume mean) | 59.4 µm |
| Mean droplet velocity | ≈0.8 m/s |
| Valid samples | 23,053 |
Phase Doppler particle analysis of water spray at 120 kHz; independent laboratory measurement.
