Abstract
A gas generating package includes tablets or other material, which when contacted with water generates both hydrogen and carbon dioxide. A catalyst for the hydrogen-oxygen reaction is applied to the exterior of the package, with the exterior of the package preferably also having applied thereto carbon dioxide and anaerobic indicators. In this manner fresh material is employed during each run requiring an anaerobic atmosphere.
Claims10
A unitary package for generating an anaerobic atmosphere for use in culturing anaerobic microorganisms, characterized by
- (a) a flexible sealed package;
- (b) material in said package for generating hydrogen;
- (c) material in said package for generating carbon dioxide;
- and
- (d) a catalyst coated onto the exterior surface of said flexible sealed package;
- (e) whereby when said package is broken and water is inserted to react with said hydrogen generating material said externally coated catalyst catalyzes the reaction between oxygen outside said package and the said generated hydrogen.
