Nephral™ ST

The reference in biocompatibility and adsorption capacity

The symmetrical structure of Nephral ST hydrogel membrane enhances its diffusion, convection & especially adsorptive properties, and contributes to efficient removal of b2-microglobunlin, AGEs, cytokines or anaphylatoxins. (1,2,3)

Systemic heparin reduction

The surface treatment of the membrane with PEI biopolymer prevents blood contact activation and binds heparin during priming with a pre-heparinized solution.  This may result in less systemic heparin being given to the patient. (4)

AFB & AFB.K therapies

Associated with Acetate Free Biofiltration therapies, Nephral ST dialyzer contributes to cardiovascular stability in patients at risk. (5)
