A ferruleis pressed by a pressing plate, and the ferruleis thereby sandwiched and fixed between a ferrule receiving partand ferrule pressing part. The pressing plateis displaced by a displacing mechanism, whereby the pressing plateis switched between a contacting state in which the pressing plateis in contact with the ferruleand a non-contacting state in which the pressing plateis not in contact with the ferruleand the ferrulecan pass thorough the inside of the ferrule pressing part. By displacement of the pressing plateto the non-contacting state, the ferrule pressing partcan be extracted from the ferruleside, and the ferrule pressing partcan therefore be removed from a columnin a state in which the ferruleis attached in a swaged fashion.

A piercer washing port is provided at a position on the trajectory of a piercer differing from the sampling position. The piercer washing port is cylindrically shaped and has an opening for inserting the piercer in the upper surface and a washing space for housing the piercer inserted from the opening. Air injection ports for injecting air and washing liquid expelling ports for expelling water serving as a washing liquid are provided on the inside wall surface of the piercer washing port. The air injection ports are provided at four locations equally spaced on the periphery along the inside wall surface of the washing space. The washing liquid expelling portsare provided at four locations equally spaced on the periphery along the inside wall surface of the washing space at different positions than those of the air injection ports.
