PROSYS INTRODUCES MEASONIC METROLGY TOOL TO CHARACTERIZE CLEANING CHEMISTRIES

The ProSys CT Cell™ Megasonic Chemistry Characterization Tool a compact machine that can not only provide a graph of the relationship of process acoustic power to Cavitations density, but can also be utilized to monitor the process fluid Cavitation properties real time.

San Francisco, July 12, 2005- ProSys Inc., the leader in advancing Megasonic cleaning technology and products, today unveiled the ProSys CT Cell™ Cavitation Metrology and monitoring tool for Megasonic Cleaning Systems Laboratory and Research applications.

"With Cavitation being acknowledged as the primary cleaning and damage mechanism, scientists need to know what their cleaning chemistries are going to do in the presence of an acoustic energy fields and a given frequency. With a processes PRE and damage characteristics optimized based upon Cavitation density, the CT Cell™ can then be used to monitor the actual fluid properties real time to make sure process parameters are being met.", said Mark Beck, Founder and CEO of ProSys. "Cavitation density and uniformity is the key to a damage free uniform process, and the CT Cell™ will help the user get their faster and stay in control"
