The PetriSphere anaerobic gas system is suitable for the culturing of anaerobic, microaerophilic and capnophilic bacteria in common anaerobic jars. Atmospheric conditions can be developed inside the jar in less than one minute, with the flexibility to choose the level of oxygen depletion. Gas extraction can be controlled to reduce risk of cell lysis. The PetriSphere system consists of a microprocessor-based controller, a diaphragm vacuum pump and a gas reservoir connection, which enables the air to be replaced with nitrogen or carbon dioxide gas. By simply pressing the start button the process starts and runs fully automatically.
