Abstract
A gas generating apparatus, for use in microorganism maintenance during sample transport, storage or incubation, comprising a container having an opening, a gas generating solid material in the container, an ampoule containing a liquid which is reactive with the solid material to produce a gas, said ampoule being openable from outside the container to free the liquid to contact the solid material, and means in the container which prevents liquid from flowing from the container after the ampoule is opened but which permits flow of gas generated in the container out of the container opening. A solid desiccant material may be put in the container to absorb water which may enter the container before the ampoule is opened, thereby preventing degradation or premature reaction of the gas generating solid material. A reducing gas, such as hydrogen, is generated alone or with carbon dioxide. The hydrogen catalytically combines with oxygen to form an anaerobic atmosphere.
