Diagram of the VFPR. Flow is split between the whole blood path and the reactive volume via a microporous membrane. Undulations of the microporous membrane fluidize the agarose-immobilized heparinase I in the reactive chamber. The membrane undulations are a result of the flow dynamics induced by the rotation rate of the inner cylinder. The treated plasma is returned to the whole blood path where it is remixed with the cell components.
