One aspect of the disclosure relates to a filtration unit intended to allow the removal of leukocytes from a fluid such as blood or a blood component, the unit containing a porous element including a medium for the removal of leukocytes by adsorption and filtration of the leukocytes, said medium including a number of layers of one and the same type which are formed from at least one porous non-woven material, in which at least one layer has been pressed by calendering prior to the stacking thereof, said at least one calendered layer being disposed on the downstream side of the stack, while the medium includes at least one non-calendered layer. The invention also relates to a bag-based system including such a unit, said system being in particular arranged for the sterile and closed-circuit filtration of the fluid.
A filtration unit for removal of leukocytes from a fluid, the filtration unit comprising an outer casing comprising:
A bag-based system for the removal of leukocytes from a fluid comprising:
An apparatus for removing leukocytes from blood or a blood component, the apparatus comprising a medium having a plurality of stacked layers of the same type, made of the same material, wherein at least one calendared layer has a reduced pore size and air permeability and increased leukocyte-retention capacity as compared to at least another non-calendared layer that is not calendared.
