This holder was flown on the Apollo 11 Command Module and was returned with unused ampules following the mission. During the extended periods of the lunar missions, clean drinking water for the astronauts was of paramount importance. Contamination was prevented by chlorinating and buffering water generated by fuel cells located in the Service Module. Chemicals were added from small ampules that fit into an injection needle system. Before use, these ampules were stored in a specially manufactured cloth holder.
NASA transferred this holder to the Smithsonian along with the rest of the contents of the Command Module in 1970.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
