A gas washing bottle. The bottle has a lower vessel and an upper vessel having first and second portions, the first portion extending into the lower vessel to provide an enclosed first space between the first portion of the upper vessel and the lower vessel. A first pipe extends from the first portion of the upper vessel and terminates adjacent the base of the lower vessel. A first barrier vessel surrounds at least part of the lower vessel to provide an enclosed second space between the first barrier vessel and the part of said lower vessel. A first communication means provides communication between the lower vessel and the enclosed second space, this communication means being positioned on the lower vessel remote from the termination of the first pipe. The first barrier vessel has a first gas connection remote from the termination of the first pipe in said lower vessel. A second barrier vessel is provided and communication is provided between the second barrier vessel and the interior of the upper vessel. A second gas connection communicates with the second barrier vessel at a position remote from the first communication means.
