Ultrasonic Homogenizers Versus High Pressure Homogenizers

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.
