Abstract

Abstract A dispensing and handling system for solutions is disclosed. The system includes a container (11) for mixing, storing and dispensing a use solution (44) through a spigot (17). The container (11) is mounted upon a cart (12), and is interconnected to a water supply conduit (16) and a concentrate solution tube (14). The concentrate solution (15) is contained within containers or bags (13). An aspirator (26) is permanently mounted within the storage container (11). The water conduit (16) and pick-up tube (14) are releasably connected to the storage container (11) by means of a quick-connect assembly (35). Also disclosed is a method for storing and handling solutions.
