Filtration unit comprises external enclosure with inlet orifice(s) and outlet orifice(s), and a porous element enclosed by the external enclosure and having deleukocytation medium. The deleukocytation medium has non-woven, porous polyurethane fabric layer. The filtration unit is operable to leukodeplete a fluid having leukocytes and platelets when the fluid flows from upstream to downstream via the filtration unit. Independent claims are also included for: (a) bag system comprising a collection bag for receiving a fluid containing platelets and having an outlet orifice, a filtration unit (1), a filtrate collection bag, a tube for providing connection from the outlet orifice of the collection bag to the inlet orifice (3) of the filtration unit, and a tube for providing connection between the outlet orifice (4) of the filtration unit and the inlet orifice of the filtrate collection bag; (b) fluid filter material comprising gas plasma-treated polyurethane; and (c) method for treating a polyurethane filter material comprising exposing the filter material to a gas plasma to increase the hydrophilicity of the filter material. |
