Compressed inert gas [e.g., argon (Ar), helium (He)] in a dedicated, cylindrical container intended to be used as the gas source for inert gas-enhanced electrosurgery. The container typically includes a tube with an opening/closing valve, and may be graded according to size (capacity) and colour-coded/labelled to denote gas content and intended use. This device is reusable until the contents of the container are exhausted.
