The INLINE steam sterilisation process

Purity enhanced — with steam

All FX-class dialyzers are sterilized by the unique INLINE steam sterilization process:  

  1. Both the blood and the dialysate compartment of the dialyzers are rinsed continuously with steam at a temperature of or above 121°C for more a minimum of 15 minutes. Rinsing with hot steam and without chemicals results in extremely low levels of residuals in the dialyzer
  2. The dialyzer is rinsed with sterile water  
  3. Every dialyzer is tested for fiber integrity using a bubble-point test  
  4. The dialyzers are dried with warm, sterile air  
  5. Finally, after drying the blood inlet and outlet ports are closed
