LIQUID SAMPLING AND TRANSFERRING APPARATUS

PURPOSE:To eliminate expanding and contracting fluctuation of an air layer in a liquid path, by providing a liquid holding container, which houses a sample solution that is withdrawn by a liquid withdrawing part through a primary transfer tube, a secondary transfer tube, which is connected to the liquid holding container, and the like. CONSTITUTION:A liquid holding container part B comprises the following devices; a primary transfer tube 14, which is connected to a supply port 3A of a constant quantity sampling tube 3; a transfer side valve 15, which is provided between the supply port 3A and the primary transfer tube 14; a liquid holding container 13, which houses the transferred liquid; an discharging tube 16, which discharges the air for transferring the sample liquid and washing liquid to the outside; and discharge valve 17. A sucking and injecting part C has a secondary transfer tube 22, which is connected to a sample supply port 13c, a transfer opening valve 36, and the like. In this constitution, the expanding and contracting fluctuation of an air layer in the liquid path is eliminated, and uniform amount of sucking and injecting the sample liquid can be secured.
