PCT No. PCT/US93/06547 Sec. 371 Date Apr. 6, 1995 Sec. 102(e) Date Apr. 6, 1995 PCT Filed Jul. 13, 1993 PCT Pub. No. WO94/01193 PCT Pub. Date Jan. 20, 1994An automated system for processing biological fluid includes a pressure differential generator, a biological fluid processing assembly including a first container operatively associated with the pressure differential generator, at least one satellite container in fluid communication with the first container and a porous medium including a leukocyte depletion medium interposed between the first container and the satellite container and a sensor downstream of the porous medium for sensing and providing a signal reflecting the presence of red blood cells downstream of the porous medium. An automated control arrangement is coupled to the sensor to receive the signal from the sensor and coupled to at least one of the pressure differential generator and the biological fluid processing assembly to control flow between the first container and the satellite container.
