A disposable anaerobic system designed for field and laboratory use.

A disposable anaerobic system which is characterized by its light weight and its compactness is described. The system consists of a multilayer plastic bag with a unique sealing device. A collapsible impregnated cardboard container is fitted with a catalyst and holders for a disposable hydrogen generator and an anaerobic indicator. The catalyst is active at room temperature and requires no heat activation. This system, which lends itself readily to compact storage, quick assembly, and ease of operation, is disposable after use.

Safe Self-contained Carbon Dioxide-Hydrogen Anaerobic System.

An anaerobic system is described which allows the microbiologist or hospital technician ease of operation not previously possible with other systems. Gas cylinders, vacuum pumps, valves, and gauges have been eliminated. A new anaerobic lid was developed that is fitted only with a snap-in rubber gasket, a double stainless-steel gauze flash arrestor, and a catalyst holder. The holder contains a palladium pellet catalyst which is active at room temperature and requires no heat for activation. This system was made specifically for use with a disposable hydrogen-carbon dioxide generator and a disposable methylene blue anaerobic indicator. In addition to ease of operation, this jar incorporates unique safety features which eliminate the possibility of a laboratory explosion. An oxygen-free atmosphere composed primarily of nitrogen and carbon dioxide was quickly achieved within the jar to insure maximal growth.
