Abstract

Centrifuge arrangement preferably intended for separation of blood and arranged for through-flow separation comprising a number of channels (4-7) for collection of at least two fractions, whereby said channels are connected to, or are arranged to be able to be connected to, an inlet (25) for the liquid which is to be fractionated and to one or more outlets (24, 26, 27) for respective fractions, whereby means are arranged to segregate at least one collection channel (e.g. 6 or 7) from other channels along at least a portion of its length, together with means for intermittently withdrawing the fraction collected in this channel. The described arrangement is characterized in that the segregatable channel is separated from remaining channels by means of one or more gaps (8, 9, 54a, 54b, 56) which are so small that an appreciable pressure difference results between this channel and remaining channels when the fraction collected in this channel is withdrawn.
