Available in single gas and multi gas mixtures across steel and aluminum cylinders in several sizes, each cylinder is factory certified to a specific concentration and expiration date. The configurations listed here cover the most commonly ordered single gases (methane, hydrogen, propane, hexane, isobutane,
