A sealed display and storage case is disclosed for viewing and storing a museum piece or the like in a protected and controlled environment. The display case includes a base having apertures therethrough, a top cover, and a bottom cover. A first seal mechanism attaches the top cover to the base, providing an upper microclimate chamber, and a second seal mechanism attaches the bottom cover to the base, providing a lower microclimate chamber. The apertures within the base limit air flow exchange between the upper and lower microclimate chambers. A rotatable disc mechanism is used to close the apertures when either cover is removed for servicing, thereby eliminating outside air flow into the unopened microclimate chamber. The humidity buffer is contained within an open vessel having an externally adjustable lid, thereby providing a way to adjust the microclimates without any outside air flow into the chambers.
