I am interested in KFM.PS Please call me back

KFM.PS capsule is based on a single-layer hydrophilic asymmetric polyethersulfone membrane with pore sizes of 0.2, 0.45 and 0.65 μm.

Highly asymmetric structure and overall increased porosity of the membrane ensures high flow rate at low differential pressure for KFM.PS Capsules. Excellent microbiological stabilization combined with low sorption towards proteins, albumins and ferments are main benefits of KFM.PS Capsules.

Designation

KFM.PS Capsules are used for preliminary, fine, polishing and sterilizing filtration of liquid media in various industries from mechanical impurities and microorganisms with the size above or equal 0.2, 0.45, 0.65 μm.

In medicine and biopharmaceutics:

  • For fine and sterilizing filtration of small volumes of parenteral preparations (LVP) with high or low pH.
  • For fine and sterilizing filtration of highly viscous media, including ophthalmological solutions.
  • For filtration of blood preparations, serums, injectable preparations containing protein, filtration of buffer solutions, for concentrating of solutions containing proteins.
  • For polishing and sterilization of small volumes of water based, pharmaceutical and biological solutions, containing a large number of colloidal particles. 
  • For concentration of protein containing solutions.
  • For filtration of buffer media.
  • For filtration of galenic preparatios
  • For filtration of process water (washing machines, filtration at points of consumption, non-pyrogenic water for injection, laboratory water purification, recycling water).

In beverage industry:

  • Supportive filtration of wines in cold bottling conditions.
  • Cold sterilization of beer.
  • Final (control) filtration of wines in conditions of "hot" filling.
  • Polishing filtration of vodkas, cognacs, colored alcoholic beverages in preparation for bottling.
  • Final filtration of mineral waters, low-alcohol and non-alcoholic drinks.
  • Microbiological stabilization of still bottled water.
  • Fine filtration of wash water.

In other industries for fine purification of liquid media from particles with a size of 0.2 microns and more.

Sanitization and sterilization 

Sterilization of Capsules is performed by autoclaving at temperature 126°С for 30 minutes after attainment of set-point temperature.

KFM.PS Capsule filter elements are able to withstand at least 10 sterilization cycles by autoclaving at P = 0,1 MPa and t=126 ± 1°С. Note! It is prohibited to sterilize Capsule by steam-in-line!

*It is necessary to perform integrity testing of Capsules after every autoclaving cycle in case of sterilizing filtration and re-using. The integrity testing can be performed using automatic integrity test devices, for example TECHNOCHECK series.

KFM.PS Capsules withstand chemical sterilization with 3% of hydrogen peroxide solution or 10% chloramine solution and hot water flushing up to 90°С. The possibility of flushing and repeated autoclaving allows reuse of Capsule filter till the end of its life time.

KFM.PS Capsules are compatible with wide variety of chemical substances.

Safety

Quality and safety

All membrane filter elements used for production of KFM.PS Capsules are subjected to wash out from organic and mechanical impurities with high-purity water and to 100% integrity control.

KFM.PS Capsules produced by Technofilter RME Ltd are added to the Register of Medical Devices of the Ministry of health of the Russian Federation.

The Capsules are certified for use in Medical Industry and Sanitary and Epidemiological Station, they are authorized to use in Food industry. 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.
