Ultrasonic cavitation is often employed for sample preparation in pharmaceutical labs.  High ultrasonic power density is ideal for these applications because it accomplishes the job quickly.  This minimizes cavitation induced heat buildup that can cause chemical degradation of samples. 

Sample prep is generally accomplished by suspending sample flasks in ultrasonic cleaners containing water and a surfactant.  Cavitation generated by ultrasonic transducers passes through the flask walls to act on the sample.  

Most equipment used in this application handles several flasks at once for production-scale operations.  An alternative design has proved especially efficient by speeding up the sample prep process in pharmaceutical research laboratories.  The secret is in the design.
