Apollo Chlorine Ampule Casing
This casing for the chlorine ampules carried aboard Apollo 11 contained a syringe to periodically inject chlorine into the water system to prevent the growth of bacteria in the spacecraft water supply. After a short time, buffer solution was added to the water to neutralize the chlorine.
