To insure that drinking water during the Apollo missions did not become contaminated with microorganisms, chemical disinfectants were periodically injected into the water supply by the astronauts. A chlorine solution was used for the Command Module. To insert the chlorine astronauts used a specially designed syringe. This item is the knob portion of the syringe system used during the historic Apollo 11 lunar landing mission. NASA transferred it to the Smithsonian in 1970.
