Fresenius Polysulfone® has been designed for blood purification only. This membrane has been clinically used since the early 1980's. Especially high flux dialyzers using Fresenius Polysulfone® have high blood compatibility and very good removal of larger molecular weight substances.
Fresenius Medical Care started to develop hollow fiber dialyzers using polyamide, however changed the material to polysulfone in 1979. In the early 1980's, the Hemofilter F60 was put on the market.
Clinical studies of Fresenius Polysulfone® dialyzers were presented at the High Permeable Membrane Symposium in Bad Homburg in May, 1984. The quality of this superior membrane is highly evaluated and has become the “golden standard” in hemodialysis today.
