An apheresis machine is provided, which can efficiently produce concentrated platelets products without excessively collecting platelets.The apheresis machine 10 comprises a centrifuge 11 having an inlet port PT1 and an outlet port PT2 for separating whole blood into a lower density component, an intermediate density component and a higher density component, a first container 18 connected to receive the lower density component from the outlet port PT2 and return it through the inlet port PT1 to the centrifuge 11, a first pump P1 operated to collect whole blood from the inlet port PT1 to the centrifuge 11, a second pump P2 operated to supply the lower density component from the first container 18, and means for variable controlling the centrifuge 11 and/or the second pump P2 for increasing or decreasing a process volume of whole blood in the centrifuge in response to at least one characteristic associated with the whole blood. |
