  • Ultrafiltration - an overview | ScienceDirect Topics

    Ultrafiltration (UF) is a separation process in which membranes with pore size of 0.1–0.001 µm are used to remove high-molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules. The attractive properties of UF include its mild operating conditions and relatively high selectivity, making it a popular method toward conventional one.

    2013-5-15 · Ultrafiltration (UF) is a commonly used biotech process for concentrating a dilute product stream. UF separates molecules in solution based on the membrane pore size or molecular weight cutoff. Diafiltration (DF) is most often used to exchange product into a desired buffer (e.g., from an elution buffer into a final formulation buffer) UF and DF ...

    Analysis using ROC curves demonstrated that UF/Wt =0.04 was a potential cut-off point for IDH both in patient with and without DM. To further verify this finding, the potential risk factors of IDH (including age, DM, and CVD) were adjusted. A UF/Wt value more than 0.04 in the dialysis prescription was found to be independently associated with IDH.
