Mass Transfer Properties. The particle size distribution of Interest In medical devices Is extremely wide, ranging from urea and electrolytes (<1 nm diameter) In hemodialysis to platelets and red cells (3 to 8 ym diameter) In plasmapheresis. Between these extremes, molecular size ranges can be defined that roughly delineate filters suitable for hemodialysis and hemofiltration (that Is, Impermeable to albumin), protein separation (that Is, albumin permeable, IgM Impermeable) and microfiltration (that Is, retentive to platelets and red cells). The lower end of these size distributions Is Indicated In Figure 1.
