Abstract
An apparatus for taking up and discharging liquid has at least one piston cylinder which responds to a command by taking up or discharging liquid, the arrangement being such that the number of liquid uptake operations is preset, with the piston cylinder being instructed to perform the discharge operation when the number of uptake operations actually performed is detected to exceed said preset number. A plurality of different liquid specimens can be mixed, and the mixture diluted when so desired, through a simple operation which assures great accuracy.
