Hemodialyzer
Features
The Filtryzer NF-U is one of the advanced high flux PMMA membranes. It offers not only excellent biocompatibility and higher adsorption capacity of proteins like as previous models, but also improved the effect of anticoagulant. In addition, NF-U series has a feature of minimized albumin leakage, and it also allows to use comfortably for patients who are concerned about malnutrition.
