Utrasonic topic: "sonication"
Sonication (also termed ultrasonication) is the application of low frequency, high intensity ultrasound waves into a liquid or pastes medium. Acoustic cavitation generated by intense sonication creates energy-dense conditions such as high pressure and temperature differentials as well as high shear forces and turbulences. Those ultrasonically generated forces break particles and droplets, disrupt cells and initiate chemical reaction. Due to these effects, sonication is used for homogenisation, wet-milling & dispersing, emulsification, extraction and sonochemistry. Read more about the manifold advantages of sonication and learn how your process can benefit from the application of power ultrasound!
