System for modifying the atmosphere within an enclosed space and incubator system including the same - System for modifying the chemical composition of atmosphere within an enclosed space and incubator system including such a system. The concentration of oxygen within the enclosed space may be either increased or decreased using an electrochemical device. The concentration of carbon dioxide within the enclosed space may be increased using an electrochemical or chemical device. As necessary, purging of the system with ambient air can be a part of the process of controlling the chemical composition of the atmosphere. The present invention obviates the need to use pressurized gas cylinders to supply atmospheric gases to the enclosed space.
