Abstract
The purpose of this report is to perform the evaluation of hemof ilter with respect to both hydraulic and solute permeability. Hydraulic permeability is usually expressed by filtration coefficient (Lp) and solute permeability by sieving coefficient (SC) of middle molecules. Both values are measured in vitro with aqueous test solution and bovine blood under the same condition. Sieving coefficient is plotted against molecular weight. Blood Lp decreases as transmembrane presure (TMP) increases. Cut off curve obteined from bovine blood experiments is located below that from aqueous solution experiments.
