Abstract
A diluent is discharged by a dispensing device into a dilution bath 11 containing a sample, and a given amount of a diluted sample 12 is sucked from the upper face by the dispensing device and discarded by discharging it into a waste fluid cup to remove many small bubbles 13 generated during the preparation of the diluted sample used for determination. The diluted sample 12 remaining in the dilution bath 11 is used for determination to improve the precision and reproducibility of determination and to prevent failure of the dispensing device due to inclusion of bubbles.
