Abstract:
1. A membrane holder for membrane adsorber chromatography comprising a housing body ( 12 ) with a reception space for at least one layer of adsorber membranes ( 22 ) and at least one first housing cap ( 34 ) for closing a first reception space opening, which can be fixed to the housing body ( 12 ), a liquid stream being introducible via first liquid guide means ( 36 ) through the first housing cap ( 34 ) and the first reception opening into the reception space, so that it passes through the adsorber membranes ( 22 ) and flows away through a second reception space opening, wherein the first housing cap ( 34 ) can be screwed as a first union nut onto the housing body ( 12 ) and a first brace element ( 24 ), which can be clamped between the first cap ( 34 ) and the housing body ( 12 ) via a flange ( 32 ) extending beyond the first reception space opening, can be fixed leaktightly in a basket-like insert ( 14 ) with a liquid-tight wall and a perforated bottom ( 18 ), which is used to receive the adsorber membranes ( 22 ), an outer contour of the basket-like insert ( 14 ) being fitted in a leaktight fashion onto an inner contour of the reception space.
