Abstract
A crossflow filtration unit for continuous diafiltration of a feed fluid for obtaining a retentate and a permeate, a corresponding method for diafiltration and the use of the crossflow filtration unit are provided. The crossflow filtration unit includes a diafiltration channel, a flat first filter material, a retentate channel, a flat second filter material, and a permeate collection channel, arranged such that the flat first filter material delimits the diafiltration channel and the retentate channel from one another, and the flat second filter material delimits the retentate channel and the permeate collection channel from one another. The diafiltration channel is fluidly connected to at least one inlet for the diafiltration medium, the retentate channel is fluidly connected to at least one inlet for the feed fluid and to at least one outlet for the retentate. The permeate collection channel is fluidly connected to at least one outlet for the permeate.
