Abstract

PURPOSE:To obtain a device of quantitative analysis with which an alteration of dispensation is easy to be done and automation is also made possible by using a rotary type dispensation setting tool instead of the use of a setting block that sets a dispensation amount. CONSTITUTION:A stated amount of dispensation is set by observing a figure 24 from a viewing window and by turning with a hand a knob 22. When a motor 10 is rotated, a piston driving tool 16 descends along a guide bar 3, a sylinge piston part 1b also goes down and thus a pump 1 absorbs a reagent 13. By rotation of the motor 10 after that, a dispensation amount setting tool 17 located under a piston part 1b ascends and into a concave part 23 prepared on it the piston part 1b is inserted. After that, the piston driving tool 16 continues to rise and discharges a reagent absorbed to the upper limit in the pump 1. In this way setting of a dispensation amount is performed by turning a cylindrical dispensation setting tool, so setting terminates in an instant and automation becomes also easy.
