A method for obtaining MNCs is set forth. The method includes: separating mononuclear cells from a biological fluid that includes red blood cells, plasma and platelets and collecting a targeted number of mononuclear cells in a suspension including plasma and residual red blood cells and platelets； concentrating the separated mononuclear cells； removing plasma from the concentrated mononuclear cells until the amount of residual plasma remaining with the concentrated mononuclear cells reaches a pre-determined volume； and adding a crystalloid solution to the concentrated mononuclear cells. Related apparatus and resultant MNC products are also disclosed.
