Method for simultaneous integrity testing of multiple hydrophobic filters (Japanese Patent)
Significantly reduce the risk management of vent filters!
In hydrophobic filter validation, only post-use integrity testing is specified, and decisions regarding the duration of use and other conditions are to be made by the user side. Generally, many cases incorporate methods to regularly confirm integrity during the usage period, such as Water Intrusion Testing (WI testing), with testing frequencies typically ranging from every few weeks to once a month. Additionally, it is common to conduct these tests only on the vent filters located on the secondary side of the liquid filtration filters. Under the current method, if an integrity test fails, it is inevitable to struggle with the sterility assurance of products manufactured during that time. This catalog introduces case studies of testing methods that allow for the simultaneous execution of multiple WI tests in a short time under normal on-site environmental conditions, thereby reducing risks to the utmost and shortening the testing intervals. *This method has been patented in Japan. *For more details, please refer to the PDF materials or feel free to contact us.
