Asahi Integrity Test Solution Kit

Overview of user integrity testing of Planova™ 15N, 20N and 35N filters using Asahi integrity test solution kits

Users are to perform two types of integrity test for Planova™ 15N, 20N and 35N filters: the Leakage Test and the Gold Particle Test. The Leakage Test is conducted before and after filter use to confirm that the filter is free from pinholes or large membrane defects. The Gold Particle Test, which is conducted by introducing colloidal gold particles matching the targeted virus sizes into the filter membrane, is performed after filter use to confirm that the fiber pore size distribution has not changed considerably during filtration. The combination of these two tests maximizes the range of detectable filter defects and thus enhances the safety and reliability of virus removal processes.
