The invention provides a method of separating liposomes or lipid complexes from a fluidic medium. The method involves passage of a fluidic medium containing liposomes or lipid complexes through a composite filter which retains the liposomes or lipid complexes while allowing the fluidic medium to pass through. The filter is composed of a ceramic membrane and a ceramic substrate that is thicker than the ceramic membrane. Moreover, the average pore size of the ceramic membrane, from about 0.1 to about 0.2 microns, is less than the average pore size of the substrate.
