Abstract
A device for diafiltration comprising a housing having an inlet, first and second outlets, a diaphragm disposed in the housing and means for sealing the diaphragm in the housing so that the material entering the inlet and not passing through the diaphragm is removed by the first outlet while the material passing through the diaphragm is removed from the housing through the second outlet characterized by the improvements of the diaphragms being formed by a plurality of capillary diaphragms arranged with the housing to require the least structural volume and each of the capillary diaphragms being an inorganic material, such as porous glass, which is chemically modified in a known manner, such as being treated with molecules including radicals, such as silane derivatives, with the functional groups.
