1. An automated biological fluid processing system comprising:

  • 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, anda porous medium comprising a red cell barrier medium or a combined leukocyte depletion/red cell barrier medium interposed between the first container and the satellite container;

    a sensor for sensing at least one fluid flow parameter, said sensor providing a signal reflecting a parameter of fluid flow through the porous medium; and

    an automated control arrangement 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.
