KFM.FG Capsule filter for liquid media filtration

KFM.FG Capsules by Technofilter RME Ltd are produced on the basis of hydrophilic PVDF membrane.  

Designation     

KFM.FG 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.

 

Main applications

In medicine and biopharmaceutics  

  • For fine and sterilizing filtration of small volumes of parenteral preparations (LVP) with high or low pH.
  • For polishing and sterilization of small volumes of water based, pharmaceutical and biological solutions, containing a large number of colloidal particles. 
  • For filtration of buffer media.
    • For filtration of galenic preparations.
  • 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

  • For finish filtration in production of small lots of beverages.
  • For ingredients filtration.
  • In experiments when choosing the optimal filtration schemes, for example in case of colored alcoholic beverages filtration.   

In other industries for fine purification of liquid media from particles with size of 0.2 µm or more.

Sanitization and sterilization

Sterilization of Capsule filters is performed by autoclaving at temperature 121°С for 30 minutes after attainment of set-point temperature.

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

*It is necessary to perform integrity testing of Capsule filters 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.FG Capsules withstand chemical sterilization with 3% of hydrogen peroxide solution or 10% chloramine solution and hot water flushing (up to 800С). The possibility of flushing and repeated autoclaving allows reuse of Capsule filter till the end of its life time.   

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

For detailed instructions on operation Capsules please contact technical specialists of Technofilter RME Ltd. 

Quality and safety 

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

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

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