Abstract
A sample introducing device, placed in the midway of an analyzing apparatus having a sample flowing route and a carrier fluid flowing route, in which device a valve disc rotatably disposed under urging force between a pair of supporting members, provided with a sample flowing passage and a carrier fluid flowing passage, in a sandwiched manner, is manually rotated with a handle so as to switch a sample flowing hole made in the valve disc for containing a predetermined amount of a sample to a position alignable with the carrier fluid flowing passage. By this simple operation of rotating the valve disc the desired amount of the sample can be transferred to the carrier fluid flowing passage, through the switching over of the sample flowing hole, for being flowed to an apparatus for analysis.
