ABSTRACT:
The invention relates to apparatus for measuring and dispensing chemical, for use primarily in a closed system for preparation of chemical solutions or mixtures, and involves a container having an input passageway for connection to a source of chemical, and a discharge passageway for connection to a source of reduced pressure. The discharge passageway is normally blocked against discharge by a valve, but has communication with the upper region of the container, whereby, upon reducing the pressure at the discharge passageway, the pressure in the upper region of the container will likewise be reduced and cause an inflow of chemical into the measuring container. Upon subsequently lifting of the valve, means are provided for exposing the upper region to atmosphere pressure whereby, the contents of the container may discharge.
