ABSTRACT:
A centrifuge, preferably a sterile laboratory centrifuge, with an intake channel for the material being centrifuged, a runoff channel for the clear phase, and a drum with a centrifuging space comprising a separation space equipped with a package of disks and a solids. The centrifuge has an initial operation that comprises introducing material to be centrifuged into the separation space and separating the solids from the clear phase, which is followed by another operation that comprises discontinuing the intake of material to be centrifuged and introducing rinse into the drum through the clear-phase runoff channel. A channel that is employed during the initial operation to supply the material to be centrifuged has two sections, between which is accommodated a valve chamber and a valve body, wherein a channel for diverting the solids extends from the periphery of the solids space to the valve chamber, and wherein the valve body is reversed to initiate the second operation, separating the second channel section, which leads from the valve chamber to the separation space, from the first channel section, connecting the solids-diversion channel to the first channel section, and allowing the solids to be extracted through the first channel section.
