ABSTRACT:
A liquid dispenser includes a plunger and an elongate barrel having a cylindrical bore which receives the plunger. The plunger includes an axial passage which delivers a volume of liquid as the plunger is depressed downwardly into the barrel. The volume of liquid delivered depends on the length of the downstroke of the plunger, and a mechanism is provided which allows the plunger to be rotated to limit the length of the downstroke to a predetermined percentage of total length. In this way, premeasured volumes of liquid may be delivered by the dispenser.
