Usually, the blood flows in the lumen side of the fibers, while the dialysate is counter-currently through the shell side. WebWith ultrafiltration (UF), filter pore size is irrelevant because the pores are so small. These filters are rated according to their nominal molecular weight limit (NMWL) or their molecular weight cutoff (MWCO). For example, a UF membrane rated at 30,000 will exclude a test protein with a molecular weight of 30,000 Daltons. bork spedition
