* For detailed instructions on wash out and sterilization of cartridges please contact technical specialists of Technofilter.
EPM.K membrane-based filter cartridges 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.K filter elements are subjected to wash out from organic and mechanical impurities with high-purity water and to 100% integrity control.
Wash out, integrity control, drying, final assembly and packaging of membrane filter cartridges is carried out in special clean rooms C and D (ISO class 6 and 7) according to the classification of clean rooms in the pharmaceutical industry.
EPM.K membrane-based 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.
