The Ultraflux® filters contain a Fresenius Polysulfone® membrane specifically developed for continuous renal replacement therapy. With this membrane, substances with a molecular weight of up to approximately 30kD can be eliminated. While plasma proteins like albumin, other large molecules and cellular blood constituents are retained. The filtration characteristics of this membrane come close to the natural human kidney’s function.
Due to their high mechanical stability and excellent filter lifetimes, the Ultraflux® filters AV paed, AV 400S, AV 600S, AV 1000S are applicable for use in all continuous renal replacement treatments.
