Disclosed is an apparatus and system for forming a slurry of gravel and fluid, preferably for injection into an oil and gas well during gravel packing operations. The apparatus includes a pressure vessel that is adapted to receive the gravel. The pressure vessel has an inlet for receiving fluid. The apparatus includes a snorkel tube that is slidingly sealingly mounted for movement into and out of the pressure vessel. The snorkel tube has an open inner end which defines the outlet of the pressure vessel and an outer end which is connected to a conduit, which is in turn is connected to the well. The pressure vessel and snorkel tube are arranged such that fluid flows in a tortuous path between the pressure vessel inlet and the inner end of the snorkel tube to entrained gravel in the flowing fluid.
