Abstract: PURPOSE:To dispense a lymphocyte simply and well, by providing a holder holding a centrifuged test tube and a sampling part holding a pipette absorbing and sampling only a lymphocyte which is seperated in this test tube and also, an illuminating part irradiating the interface of the lymphocyte. CONSTITUTION:A test tube 3 holding the centrifuged blood is held on a holder 2 of a mechanism 1 attached an up and down adjusting tongs 4 and a rotation adjusting tongs 5. On one hand, a stand 6 is provided on the back of the mechanism 1 and a pipette 10 and a pipette pump 8, are held by a holder 9 on this upper part. Further, a motor 11 setting a roller 12 to its shaft for driving the pump 8 is attached to a motor stand 13 and also, a lamp 15 for lymphocyte interface illumination of the test tube is attached. Sample blood is centrifuged and the tip end of the pipette 10 is positioned only on a lymphocyte layer 19 among 18, each layer separated in an erythrocyte layer 17, a specific gravity liquid layer 18, the layer 19 and a blood serum layer 20 and only the lymphocyte is sampled well by driving the pump 8.
