A hemodialyzer having a reinforced blood side case half and a reinforced dialysate side case half, said case halves having generally trapezoidal cross sections with the longer sides being open and joinable together in the assembled form along a parting line. Wedge elements extending within said case halves positioned with their apexes at said parting line. The base walls of the wedges and case halves define together a generally rectangular cavity in which a stack of pleated cofolded semipermeable membrane and dialysate permeable separator is positioned. The last pleat of the membrane on either side of the stack extends over the end of the adjacent wedge element on the blood side and is trapped and adhesively sealed between the side walls of the blood side case half and the coextending wall of the wedge element. The dialysate side of the stack is sealed to the base wall of the dialysate side case half by a non-adherent solid preformed body of resilient elastomeric material. The coextending wedge element and case half sides are contoured so as to permit accurate measurement and positioning of initially flowable curable in situ adhesive.
