Both technologies are solid choices for particle size reduction applications, although ultrasonic homogenizers can achieve smaller sizes (below 100 nm) than high pressure homogenizers (roughly 100 nm for higher-pressure units). If you're dealing with high-viscosity samples, high pressure homogenization will be more suitable.
