Abstract: Display device (1) having a transparent body (2), with the display device (1) having a self-contained, self-illuminating light source (3), characterized in that the light source (3) is embedded in the transparent body (2), with light emitted by the light source (3) being retained in the transparent body (2) by total internal reflection at the boundary surfaces (4, 5, 6, 7) of the transparent body (2) and the transparent body (2) further comprises at least one light output side (8) having at least one light output structure, formed by at least one elevation (9) and/or at least one recess (10) in a surface of the transparent body (2), for outputting light of the self-illuminating light source (3).

Abstract: The invention relates to a centrifuge cartridge (1) for a centrifuge (2) for the separation of a mixture (3) into a solid cake (4) and into a liquid phase 5), with the centrifuge cartridge (1) being rotatably supported around an axis of rotation (6) of the centrifuge (2) in the installed state. The centrifuge cartridge (1) is releasably installed in the centrifuge (2), in particular in a centrifuge drum (21) of the centrifuge (2).
