Filtration apparatus for the filtration of liquids, in particular by means of reduced pressure or overpressure

摘要

Such filter apparatuses are used in laboratories, for example for residue analyses. They have a receiving vessel 11 for the liquid to be filtered and an outlet part 12 for the filtrate, and in addition a filter plate 18 installed in a sealed manner between these parts. This filter plate 18 sits in a plastic holder, which was hitherto clamped, sealed, by an extra O-ring gasket between the receiving vessel 11 and the outlet part 12. In order to achieve a structural simplification, according to the invention the plastic holder for the filter plate 18 is at the same time constructed as an annular gasket 19 which is preferably thermally shrunk onto the periphery of the filter plate 18.
