Abstract
Apparatus for automatically dispensing accurately a predetermined quantity of a liquid required to be stored at room temperature including a syringe pump, a liquid tank, and a pump displacement mechanism for moving the syringe pump between the liquid tank and a container. The piston of the syringe pump is displaced by a piston displacement mechanism. A weigher measures weights of the tank and liquid in the tank as well as a draining system for draining the liquid of the liquid tank. Liquid is supplied to the liquid tank from a supply system. A control device controls displacement of the syringe pump and the piston of the syringe pump, actuation of the supply system and the drainage system, and reads measurement output signals of the weigher.
