Apparatus for centrifuging of a liquid packaged in flexible-walled bags connected to at least one filter

A device for treatment by centrifuging of a liquid package in a plurality of flexible-walled bags which are connected via a flexible tube to at least one filter of substantially flat shape with opposite faces, according to which the bags are placed, with the filter, in a confinement space which is rotated about a central rotation axis passing through said space, wherein said at least one filter is placed in said faces of said at least one filter parallel to said central rotation axis, and said bags are respectively placed on said opposite faces of said at least one filter in said device and including a centrifuging support container having an open side constructed and arranged to be driven in rotation at high speed about said central rotation axis, and which defines said confinement space, wherein the support includes means for supporting and positioning at least one filter and for constituting with the latter a partition of plane general shape, passed through substantially in its mid-plane by said central rotation axis and subdividing the internal volume of the support into two compartments constructed and arranged to contain said bags.
