Ultrasonic Nicotine Extraction Machine

The disintegration of cell structures by means of ultrasound is used for the extraction of intra-cellular compounds or for the microbial inactivation. Background In microbiology, ultrasound is primarily associated with cell disruption or disintegration. 

When sonicating liquids at high intensities, the sound waves that propagate into the liquid media result in alternating high-pressure (compression) and low-pressure (rarefaction) cycles, with rates depending on the frequency. During the low-pressure cycle, high-intensity ultrasonic waves create small vacuum bubbles or voids in the liquid. 

When the bubbles attain a volume at which they can no longer absorb energy, they collapse violently during a high-pressure cycle. This phenomenon is termed cavitation.
