Abstract
A compensating plate for a pressure filtration cell including a generally cylindrical liquid-feeding vessel and a base removably connected to the feeding vessel by means of a flanged joint, the removable base forming a filter holder, in which an outer edge of the plate is engaged in a flange between the liquid-feeding vessel and the filter holder and, on its upper side, the outer edge of the plate is sealed against the liquid-feeding vessel by means of a circumferential seal. The compensating plate has a central opening corresponding to the size of a filter placed in the filter holder, the plate having a slight conical depression toward the said opening. The opening passes into a downwardly extending cylindrical frame whose bottom edge presses the filter or a filter packing against the filter holder in a sealing manner when the filter holder and the liquid-feeding vessel are forced axially toward one another such that the compensating plate functions as a seal between the liquid-feeding vessel and the filter holder formed by the removable base.
