Cavitation in Ultrasonic Cleaning and Cell Disruption

It is important to quantify the cavitation energy in all applications ranging from ultrasonic cleaners to cell disruptors.  A cavitation meter measures the energy intensity and frequency within ultrasonic and single wafer cleaners, including probes with side-mounted sensors that can be placed within the megasonic jet streams, as well as those resembling a beaker to quantify the energy emanating from the ultrasonic horns used for cell disruption and homogenizing.  Lawrence Azar (February 2009 issue of Controlled Environments Magazine)
Understanding and Evaluating Ultrasonic and Megasonic Cleaners

Achieving perfect uniformity within a bath has been elusive and assuring one is operating between effective levels is critical. Using the cavitation meter as a process control tool will improve both the yield and throughput of the cleaning operations.  Lawrence Azar  (September/October 2007 issue of Process Cleaning Magazine)
Since 1996, ppb has been the leader in providing solutions to your Ultrasonic
and Megasonic cleaning efficiency concerns. With ever decreasing dimensions or need for quality assurance,
the understanding and analysis of your cleaners has never been more critical.

Our advanced line of cavitation metrology
instruments have been proven to increase yield by accurately measuring the
energy and frequency in Ultrasonic and Megasonic cleaning baths, nozzle
streams and films, and cell disruptors and
homegenizers 

Our digital hand-held meters allow users to map the in-situ energy distribution, establish tank-to-tank uniformity, and
identify de-bonded or failed transducers. This is accomplished through our
advance sensor and signal processing design, which captures the cavitation
implosion and the driving acoustic signatures.

Our probes provide an accurate and repeatable measure that incorporates
such solution variables as temperature, vapor pressure, surface tension, and flow
rate. Continuos monitoring is also possible with our Monitoring-Transmitter. NIST Traceable Calibration available.
