Laboratory incubators designed to maintain a controlled and suitable oxygen-free (i.e., anaerobic) environment in a pre-determined range of temperatures. These incubators typically consist of a chamber, a vacuum system to extract the air, a heating system, and a reusable or disposable gas mixture supply (e.g., a gas typically including hydrogen and nitrogen dioxide) generator or gas tank to fill the chamber after the extraction of the air. The incubators usually include a thermostat, a temperature display, an oxygen concentration sensor, and alarms; they may also include humidity controls, recorders, carbon dioxide injectors, and other accessories. Small anaerobic incubators using several different types of jar and lid arrangements that may use different means to remove the oxygen (including a catalyst) are also available. Anaerobic laboratory incubators are mainly used for growing pathologic anaerobic microorganisms; they are frequently attached to anaerobic chambers or anaerobic glove boxes.
