We offer a complete line of floating piston and rodded transfer vessels. These vessels can be used for a variety of purposes and applications. These vessels have been used for Petroleum Core Flooding experiments, Supercritical Carbon Dioxide, PVT experiments, Catalysis, Polymerization, Oxidation, Hydrogenations, and other Reactor studies. In an experiment where multiple fluids or phases are to be injected into the system, a series of accumulators are installed into the system and then only one metering pump is required to inject the fluids in sequence. These vessels also protect the metering pumps from highly corrosive or high brine liquids, so that the precision metering pump is not damaged.
