Schematic representation of the ultrafiltration circuit for concentrating fibrinogen and other coagulation factors in FFP using an ultrafilter pump. FFP was circulated using a dialyzer with a polysulfone-based membrane to remove plasma fluid through a convective process involving filtration across membranes. The ultrafilter pump ran at a flow rate of 300 mL/min to remove plasma water using a hollow fiber.
