BENCH DP0150-3

The Pulse 650™ is supplied with the 6mm horn as standard, for processing samples from 10-100mL. Six horns, from 2mm to 12mm, are available to meet sample volume requirements. The Pulse 650™ is supplied with the 6mm horn as standard, for processing samples from 10-100mL. Choosing the right homogenizer horn is an important step in most ultrasonic homogenization applications. Also known as a probe, the horn is inserted into the sample and vibrates rapidly. This transfers ultrasonic energy to the sample; specifically, the particles in close proximity to the horn are blasted with huge amounts of energy. The energy blast, and the vacuum formed each time the probe retracts during its vibrational movement, causes the formation and collapse of bubbles in the surrounding liquid, a process known as cavitation. Cavitation creates shear and shock waves, which facilitate a range of applications including cell disruption, particle size reduction, emulsification, and dispersion.
