A separator for centrifugally processing includes a rotatable drum having at least two drum parts, which can be rotated relative to one another at a screw thread. A drum tool is designed to open and close the drum by rotating the drum parts screwed together by the screw thread. The drum tool includes a retaining element attachable to the one drum part, a driver element attachable to the other, relatively rotatable drum part, and at least one rotation device for the relative rotation between the retaining element and the driver element together with the drum parts. The retaining and driver elements each having two or more points of engagement for the rotation device. The points of engagement are symmetrically arranged in such a way that forces produced by the rotation device produce a torque for the relative rotation of the drum parts, but no resulting force acting on the screwed drum parts on one side is produced.

Embodiments are directed to methods and apparatuses for ensuring that mechanisms that are used to position components of an apheresis machine are not broken as a result of rotation of a centrifuge. In embodiments, a safety mechanism is provided that contacts components of the centrifuge and pushes them into a position to ensure that they do not break when the centrifuge is operated at high rpm.

A solid-bowl centrifuge screw with a screw flight is provided. The screw flight has at least a first welding layer on a base body of the solid-bowl centrifuge and at least a second welding layer on the first welding layer. Thus, plural welding layers are disposed successively on one another and are applied by shaping build-up welding.

A tri-axial centrifuge apparatus for testing of petro-physical properties of a test sample includes a tri-axial sample holder located within an inner bore of a cell body. An axial pressure fluid supply line delivers an axial pressure fluid to apply an axial pressure on the test sample. A confining pressure fluid supply line delivers a confining pressure fluid to apply a biaxial confining pressure on the test sample. A test fluid holder contains test fluid and is static relative to the cell body. The axial pressure fluid, the confining pressure fluid, and the test fluid are contained in separate flow systems. A centrifuge has a window that is located on a portion of a path of the tri-axial sample holder. The tri-axial sample holder is loaded in the centrifuge and spinning with the centrifuge. An x-ray instrument is static and is aligned with the window of the centrifuge.
