The object of the present invention is to provide a cartridge filter with the use of a hydrophilic microporous filter membrane excellent in chemical resistance which is appropriately usable in, for example, processes for producing semiconductors and drugs. A microfilter cartridge is described wherein a microporous filter membrane (3), membrane supports (2,4), a core (5), an outer cover (1) and end-plates (6a,6b) constituting the filter cartridge are all made of a polysulfone polymer. <IMAGE> |
