<p>This invention is directed to suck as quickly as possible an erythrocyte component as a highly viscous liquid when a blood plasma component and the erythrocyte component are pipetted from a blood sample in which the blood plasma component and the erythrocyte component are separated into upper and lower fractions by centrifugal separation. A nozzle portion (32) consists of a nozzle base (35) and a disposable chip (36) and is transferred vertically and horizontally by an XYZ robot (34). Pipetting of the blood plasma component in the blood sample place into a test tube (62) by the nozzle portion (32) is first carried out and after the inner wall of the disposable chip (36) is coated by the blood plasma, pipetting of the erythrocyte component is then carried out.</p> |
