Dry/lock storage cabinet is made-up of painted steel to provide an environment for storage of endoscopes that is free of absorbent material to discourage bacterial and/or fungal growth. It is designed to accommodate up to eight endoscopes. A gasket surrounds the door opening. When the door is closed the gasket is compressed providing a sealed enclosure. At the top of the cabinet is an enclosure containing an air pump for the circulation of the dehumidified air through the channels preceding the air pump. It contains desiccant bags, which remove the moisture from the re-circulated air.
