Abstract
An apparatus and method for sterilizing items includes a sterilizing chamber that is evacuated. A refrigerant in liquid form expands within the evacuated chamber and rapidly reduces the temperature on the surface of any of the items within the chamber. Thereafter the temperature may rapidly return to room temperature. The rapid temperature changes effectively kill any organisms at or near the surface of any of the items within the chamber.
