Abstract
A centrifuge chamber of a cell separator having a separation channel with an inlet to introduce the cell suspension and at least one outlet to withdraw a fraction of the cell suspension is described. The cell suspension can be blood. The separation channel is shaped like a spiral extending from the radially outer end of the channel to the radially inner end of the channel, with a progressive slope. The centrifuge chamber allows a uniform, contaminant free separation of the cell suspension into its components.
