초록

An improved solvent handling system for use with a liquid chromatograph is disclosed in which a manifold allows a source of pressurized gas to communicate with a plurality of solvent vessels. Individual check valves prevent return flow into the manifold and cross flow between the solvent vessels. A pressure equalization system is also provided for equalizing the pressure between each solvent vessel and the corresponding supply conduit. An individually manually operated vent is provided for sparging and pressure release.
