    Abstract: Purpose: to judge shortage of a discharge quantity, by identifying the presence of any bubbles at the time of discharge. Constitution: characteristics (101) involving bubbles provides a different internal pressure of a nozzle at nearly the end of discharge of a sample than that provided by characteristics (100) not involving bubbles. The nozzle internal pressure is detected at the time of judgement (105), and this detection value is compared with a threshold value. Accordingly, the occurrence of the bubbles can be judged, and shortage of a discharge quantity is judged on the basis of this judgement to give an alarm.

    Abstract: ( ) A viscosity measurement is carried out simultaneously during aspiration of red blood cell component in an blood sample pipetting apparatus. In a red blood cell pipetting process. a control unit 84 causes a piston 76 to be pulled downwardly so as to produce a predetermined initial aspiration pressure. A pressure sensor 54 monitors an inner pressure of an air tube 44. A viscosity measuring unit 86 measures a time required from a point of time when the initial aspiration pressure is produced, to a point of time when the pressure reaches a predetermined pressure value .beta., and the unit 86 obtains the viscosity of the red blood cell component by comparing the required time with a table 88. The table 88 stores data corresponding to the relationship between the required time and the viscosity, which is approximately proportional. 13
