ABSTRACT:
An apparatus for drawing liquid samples and the like into an analytical testing machine, which includes a vertically extending guide rail fixed to a base, a movable support member slidably mounted on the guide rail for movement between an upper position and a lower position, a stopper for blocking movement of the movable support member above the upper position, an arm holding a probe at an end thereof and pivotally mounted to the movable support member at the other end, an arciform guide projecting from a pivot member so as to engage the upper surface of a fixed support member when the movable support member in its upper position and the arm is pivoted upward, and a detent mechanism fixed to the movable support member and elastically engageable with the pivot member for releasably holding the arm in a first predetermined inclination. When the movable support member is in its upper position, the arm is pivotable upward to a second predetermined inclination so as to bring the arciform guide into a position where it is vertically supported by the fixed support member.
