EPM.РР filter elements are produced on the basis of highly porous polypropylene hydrophobic membrane that provides excellent chemical compatibility in a wide range of applications. High thermal resistance and hydrophobic nature of the polypropylene membrane makes it the best choice for such industrial processes as filtration of gases, air, aggressive media, for various chemical processes, for production of photosensitive resists and other industrial applications. EPM.PP filter cartridges have high flow rate and chemical compatibility.

EPM.PP membrane-based filter elements are produced in accordance with the regulatory technical documents on product quality and are certified for use in the filtration processes of biopharmaceutical solutions. All EPM.PP filter elements are subjected to purging from mechanical impurities with high-purity air and to 100% integrity control. Control is performed with the “dry” method using aerosol particles (test for Permeability of aerosol particles with size 0,2-0,3 μm). This test fully correlates with the test for sterilization capability using the aerosol containing Brevundimonas Diminuta bacteria with the concentration of 2х1010 CFU/cm2. For testing parameters, please contact TECHNOFILTER technical specialists.
Final assembly and packaging of membrane filter cartridges is carried out in special clean rooms (ISO class 6 and 7) according to the classification of clean rooms in the pharmaceutical industry in accordance with EU GGMP.
EPM.PP membrane-based filter elements undergo tests for bacterial and toxicological safety, materials used in the construction of filters have a minimal amount of extractable components and are approved for contact with intravenous drugs and food. Safety of filter cartridges is determined by a series of sanitary and chemical tests, and toxicology tests in compliance with GOST R ISO 10993.1-99, GOST R ISO 10993.5-99, GOST R ISO 10993.10-00.
