A process is disclosed for operating a centrifugation unit with a centrifugation container, in particular a centrifugation bowl, for separating the components of a liquid, in particular blood, containing components with different specific weights. The centrifugation container has a separation chamber, a liquid inlet into the separation chamber and an outlet for discharging the separated component from the separation chamber. The inlet and the outlet extend through a revolving passage at the upper end of the container. The inlet is in communication with an inlet duct which opens in a defined area of the container into the separation chamber. A pumping device is provided for filling and/or emptying the centrifugation container. The liquid to be centrifuged is supplied through the inlet. After a desired amount is separated, the flow direction between inlet and outlet is reversed while the centrifugation container continues to rotate at its full working speed, so that at least one of the separated components is discharged from the separation chamber through the inlet duct and the inlet. The flow direction is then reversed again, so that liquid to be separated is again supplied through the inlet. While the separated component is discharged, a compensating liquid is supplied through the outlet in communication with the separation chamber. Also disclosed is a corresponding centrifugation unit. |
