The 27351-000 consists of a brass cooling vessel with built-in 20 ft. (6m) copper cooling coil. Includes compression fittings and 1⁄8" needle valve at the downstream end. The volatility of liquefied petroleum (LP) gases is determined by allowing a precooled sample to weather under specified conditions and observing the temperature when 95% has evaporated. Residues in LP gases are determined by weathering of a precooled sample and determination of the volume remaining at 100°F (37.8°C).
