1. A blood processing system comprising a source of blood cells, a blood cell storage container, a source of an additive solution for blood cells, a blood component collection flow channel communicating with the blood cell storage container and including an in-line filter to remove leukocytes from blood cells before entering the blood cell storage container, a pumping mechanism communicating with the blood component collection flow channel, and a controller to operate the pumping mechanism in different modes, including a first mode to convey blood cells from the blood cell source into the blood component collection flow channel and a second mode for conveying additive solution from the additive solution source into the blood component collection flow channel, the controller including a function to alternate the first and second modes.
