PROBLEM TO BE SOLVED: To provide a sample supplying device capable of substituting a sample solution after measurement for a new one without being contaminated by the residual sample solution while a measurement site is continuously being dipped into the sample solution even in a small amount of sample solution.;SOLUTION: The volume of the channel between a tip section and a flow cell 2 while the tip section of a discharging device 6 adheres to an inlet 5 for pouring the sample solution is set to 0.2 times or more and 5 times or less than that of the flow cell 2. Additionally, a weir 7 for preventing a back-flow is provided between an outlet 4 for discharging the sample solution from the flow cell 2 and a discharge section 8 for discarding the discharged sample solution. The sample solution is supplied for filling the inside of the flow cell 2 with the sample solution and the sample solution after the measurement is pushed out to the discharge section 8, thus simultaneously performing the supply of the sample solution, the discharge of the sample solution after the measurement, and the cleaning of the flow cell 2.;COPYRIGHT: (C)2005,JPO&NCIPI
