EPM.PS filter elements are produced on the basis of the one-layer hydrophilic asymmetric polyethersulphone membrane with the micron ratings of 0.2, 0.45 and 0.8 μm. The special pore structure ensures uniform clogging of the membrane and makes it much easier to filter viscous liquids. Increased overall porosity of the membrane combined with high thermal and chemical resistance ensures high flow rate and reliable removal of mechanical particles, bacteria, suspended matters and colloids from liquids in a wide range of pH. 

Extremely low absorption of the polyethersulphone membrane makes EPM.PS the best choice for application in the processes of filtration of protein-containing solutions and biological liquids, especially in biopharmaceutical industry and beverages industry.

Safety

EPM.PS 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.PS 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 (ISO class 5, 6 and 7) according to the classification of clean rooms in the pharmaceutical industry in accordance with EU GGMP.

EPM.PS 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 elements 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.

Integrity test 

In the course of testing each membrane-based filter element is integrity tested by the non-destructive physical method of determination of rate of air passing through the water wetted membrane.

Bacterial endotoxins (pyrogenicity)

Filtrate samples are examined for bacterial endotoxin (BE) content using the LAL test. BE content – 0.05 EU/ml, the allowable value for water intended for preparation of injection solutions is less than 0.25 EU/ml.
