Abstract

The invention relates to a centrifuge arrangement having a centrifuge rotor comprising a drive disc (18) connected to a drive source. Furthermore, the centrifuge rotor comprises at least one separation container (1, 32) which comprises a separation passage (6) and a separation chamber (9) whose outlet and inlet passages lead to the center of the drive disc (18). Advantageously, the separation container (1, 32) is made as self-supporting part of rigid or semi-rigid but flexible material and this makes it possible to insert said container easily into the drive disc (18) and in addition provides advantages in the production of the centrifuge arrangement according to the invention.
