Zusammenfassung:A method for degassing a cross-flow diafiltration unit, a cross-flow diafiltration method and a cross-flow diafiltration unit. The degassing method includes (i) providing a cross-flow diafiltration unit having a diafiltration channel, a retentate channel and a permeate channel, a first filter material that delimits the diafiltration channel from the retentate channel, and a second filter material that delimits the retentate channel from the permeate channel; and thereafter (ii) feeding a liquid into the retentate channel so that the liquid flows in a flow direction through the retentate channel and penetrates through the first filter material into the diafiltration channel, whereby the retentate channel and the diafiltration channel are filled with and degassed by the liquid.
