Abstract

A centrifuge comprises a casing (2) and a rotor (1) mounted on a bearing (4) for rotation inside the casing. Inside a circumferential wall (12) of a bowl of the rotor (1) there are arranged in an axial sequence: a settlement zone where fluid can collect, an annular weir (13) projecting radially inwards, and an escape zone (14) where fluid can flow out of the bowl. The escape zone may comprise a set of holes (15) through the wall (12) in the base of an annular gulley (14). The bowl of the rotor (1) rotates in a chamber of the casing (2) and an annular seal (5) between the rotor (1) and the casing (2) divides the chamber into two parts (17, 18) to prevent fluid from reaching the bearing (4). Air ducts (19) may connect the two parts of the chamber to equalize the pressure between them. The centrifuge can be manufactured as a small, disposable unit designed to work with an external drive.
