Abstract: A device for disinfecting and storing endoscopes and the like includes a pair of vertically spaced, wall-mounted brackets between which extend a plurality of parallel connecting rods for supporting the brackets in fixed position relative to each other. A pair of vertically extending tubes for holding disinfecting liquid are locked in position between the brackets by a pair of annular cam-action nuts engaging the top ends of the tubes, the nuts being rotatable to release the tubes for removal and cleaning at a remote location. Elastomeric plugs inserted into the bottom ends of the tubes preclude leakage of disinfecting liquid therefrom. Alternatively, valve assemblies can be provided at the bottom ends of the tubes to permit drainage of the disinfecting liquid from the tubes when in their mounted positions. The uppermost bracket supports the annular nuts which in turn support one or two endoscopes with their insertion portions extending through the annular nuts into the disinfecting liquid within the tubes.
