A method for processing a biological fluid comprises passing a biological fluid through a leukocyte depletion filter assembly and into a container downstream of the filter assembly; and separating gas displaced by the biological fluid into the downstream container by passing the gas from the container through a liquid barrier medium in a gas collection and displacement loop. Devices for carrying out the methods are also disclosed. |
