Abstract: A method and assembly for treating hazardous and/or unknown fluids either liquids or compressed gases contained in a gas cylinder (12) having a cylinder body (14) and a removable fixture (16). The assembly (10) includes a tubular housing (18) having an open end (20). An adjustable carriage assembly (34, 38, 40) is included for supporting the cylinder body (14) in the center of the housing (18). A clamping assembly (30) secures the cylinder body (14) to the carriage assembly (34, 38, 42). An end cap (70) seals the open end (20) of the housing (18). A shaft (72) is rotatably disposed through the end cap (70). The shaft (72) includes a fixture engagement assembly (78) on one end (76) thereof for engaging a portion of the fixture (16) and imparting a rotational force thereto. A motor driven gear box (86) imparts the rotational force to another end (74) of the shaft (72 ).

Abstract: A portable apparatus and method for collecting and testing ground water samples including a container (12) defining a chamber (14) in which a control atmosphere is established. A valve means (22) is included which is capable of bypassing water away from the chamber (14) and continuously admitting water samples to the chamber (14). A preferred method of collecting a ground water sample includes the steps of establishing a controlled atmosphere in the chamber (14), directing the flow of water into the chamber (14), collecting the water sample inside the chamber (14), and testing the sample inside the chamber (14) to prevent contamination from the air on the exterior of the chamber (14).
