KFM.K+ Capsule filter for liquid media filtration

KFM.K Capsules by Technofilter RME Ltd are produced on the basis of hydrophilic polyamide membrane (Nylon 6+66) with positive Zeta-potential.  

Main applications

In medicine and biopharmacy

  • For polishing and sterilization of small and medium volumes injectables, infusion solutions, culture medium.
  • For removal of bacterial endotoxins (pyrogens) from aqueous solutions.
  • For finish treatment of water for injection.
  • For replacing disc filters 293 mm diameter.

In microelectronics

  • In ultra pure water points-of-use (removal of bacteria and colloids).

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.K+ Capsule filters are able to withstand at least 5 sterilization cycles by autoclaving at P = 0,1 MPa and t=121 ± 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.K 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.K+ 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.
