The invention relates to a device for the separation of a fluid into at least two fractions, using a plurality of membrane filters, and to the use thereof. The inventive device comprises at least one sub-assembly () of membrane support plates (), with a filter membrane () being fixed to each of the opposing faces of the above-mentioned plates. According to the invention, the filter membrane is fixed to a part of the membrane support plate () that comprises means for guiding a first fraction of the fluid passing through the membranes () towards channels which are used to release said first fluid fraction and which are disposed in a lateral part of the plate (). Moreover, the first fraction of the fluid is recovered inside a recovery space between the membrane () and one face of the membrane support plate (). The membrane support plates () of each of the sub-assemblies () are assembled to one another in an adjacent manner. Two adjacent plates () define a fluid circulation space () between the two membranes () which are fixed to opposing faces of two adjacent plates (). The channels used to release the first fluid passing through the membranes () comprise, for each of the membrane support plates of the assembly () and for each of the first fluid recovery spaces, one portion which is disposed inside a rigid transparent part (). The aforementioned rigid transparent part is adjacent to a lateral longitudinal edge of the membrane support plate () which is associated with a sealing means (). Furthermore, said sealing means can be actuated in order to stop the fluid from flowing into a corresponding recovery space.
