    Abstract: The stability of bicarbonate dialysate is maintained over a prolonged period by maintaining a blanket of CO.sub.2 at atmospheric pressure over the solution in an air-tight storage tank having a non-leaching interior. The CO.sub.2 blanket is kept at atmospheric pressure in the storage tank by use of a negative pressure regulator connected to the CO.sub.2 gas cylinder.
