Dialysers and filters

Ultraflux® filters contain a Polysulfone® membrane which has been developed by Fresenius Medical Care specifically for continuous renal replacement therapy.

These have been designed to:

  • Have similar filtration characteristics to those of the human kidney glomeruli
  • Retain cellular blood components, including plasma proteins, such as albumin, coagulation factors and immunoglobulins
  • Have a long lifespan
  • Be easy to use
  • Have high biocompatibility
  • Be mechanically stable
  • Have individually selectable filter sizes

Plasma Filters

PlasmaFlux PSu filters from Fresenius Medical Care enable the elimination of a wide range of substances due to a sieving coefficient of 1 for molecules with a molecular weight of up to 2 million daltons. PlasmaFlux PSu filters contain the polysulfone-based Plasmasulfone® membrane, which has been designed to minimise the activation of the patient’s immune system during blood–­membrane interaction.
