APPARATUS FOR RAPID FILTRATION, ESPECIALLY FOR BIOLOGICAL LIQUIDS

摘要

Fast filtering apparatus, particularly for biological liquids. It comprises in combination: an injection device equipped with a cylindrical reservoir, whose bottom is sealed by a porous pellet and whose top is sealed by a piston displaceable in translation in the cylindrical reservoir, the latter containing the liquid phase to be filtered; a filter support device comprising a cylindrical chamber, whose upper part is sealed by a porous pellet serving as a support for the actual filtering material; a device for bringing about the fast, temporary contact between the injection device and the filter support device; an electronic control assembly controlling each filtering operation, by simultaneously acting on the contacting device and on the mechanical means for the translation of the piston.
