PURPOSE:To enable the checking of waste consumption of a washing liquid and an increase in a waste liquor by determining the optimum washing conditions corresponding to a member to be washed of a distribution probe or the like based on information on a sample to be analyzed to control a flow rate of the washing liquid. CONSTITUTION:As a member 29 to be washed such as a distribution probe or stirring bar moves to a washing part container 26 from a reaction container 33, a washing liquid 21 in a washing liquid container 22 is sucked with a pump device 24 and discharged to the container 26 through a transfer pipe 23 to wash the member 29. Then, the washing liquid contaminated after the washing is gathered to a waste liquor container 27 as waste liquor 28. Here, information on a sample to be analyzed, for example, information on whether the sample is for analysis on biochemical items or immunological items is included on a work sheet 5 to be inputted 61 into an arithmetic device 7 beforehand. The arithmetic device 7 picks up and processes information corresponding to the member 29 to determine the optimum washing conditions, which are sent to a controller 2. The controller 2 controls a three-way valve 32 according to the information to regulate a flow rate of the washing liquid 21 flowing into the container 26. |
