Abstract: Blood separation media include a fibrous web formed by 50 to 99 parts by weight of glass microfibers, and 1 to 50 parts by weight of fibrillated fibers; a polymeric, hydrophilic binder; a wetting agent; and a salt. The binder covers at least a part of the glass microfibers, and the web is further impregnated with a wetting agent and it contains a salt which is capable of crenating red blood cells. The pore size of the media is smaller than the average pore size of red blood cells. Compared to conventional separation media, the invention will improve efficiency of the separation of the red blood cells from the plasma and increase the speed and volume of the separated material. The present invention also provides for a decrease in lysing of the red blood cells during the filtration process which gives improved purity of the material.
