A device (1) for fractionating particles (P) contained in a liquid (M) on the basis of the masses thereof comprises a plurality of cantilevers (2, 2.1, 2.2, 2.3), which are respectively mounted at one end and have a free end (2a), wherein each cantilever (2, 2.1, 2.2, 2.3) has a fluid channel (3, 3.1, 3.2, 3.3), in particular of a U shape, and the fluid channels of the cantilevers are arranged in series. The cantilevers (2, 2.1, 2.2, 2.3) can be made to vibrate by at least one vibration generator (5, 5', 5''). The centrifugal forces (Fcent) and/or frictional forces (Fdrag) exerted on the particle-charged liquid (M) flowing in the fluid channel as a result of the vibrations of the respective cantilever (2, 2.1, 2.2, 2.3) are set differently for each cantilever (2, 2.1, 2.2, 2.3). |
