GasPak anaerobic system is used to create an oxygen-free environment for the growth of anaerobic microorganisms. At present, it is the most commonly used method for anaerobiosis. It is very simple to perform and is perfect for a laboratory having less sample load. Inoculated plates or tubes are placed inside the polycarbonate jar or anaerobic container along with gas generator sachet and indicator strip and is sealed completely. In the presence of water, chemicals present inside the sachet i.

The availability of gas supply is another major drawback of this system. Currently, it is being replaced by a more convenient GasPak system. The lid can be clamped airtight with a screw and is fitted with two tubes with taps, one for the introduction of the gas inside inlet and the other as an outlet for the vacuum valve. The lid also contains two terminals that can be connected to an electric supply. A capsule containing alumina pellets coated with palladium palladinised alumina is suspended under the lid by stout wires which are connected with the terminals to heat the catalyst for its activity. Nowadays, catalysts that are active at room temperature are also available. It is practically impossible to evacuate all the air so some amount of oxygen will still be left behind. The residual oxygen left behind is converted to water using spongy palladium or platinum catalyst. The catalyst acts as a catalyzing agent causing slow combination of hydrogen and oxygen to form water. Reduced methylene blue is generally used as an indicator mixture of NaOH, methylene blue, and glucose. It becomes colorless anaerobically but regains blue color on exposure to oxygen. Reduced methylene blue indicator is used to check the efficacy of anaerobiosis. A tube containing reduced methylene blue solution had to kept inside the jar along with the culture plates.

McIntosh and Fildes' anaerobic jar is an instrument used in the production of an anaerobic environment. This method of anaerobiosis as others is used to culture bacteria which die or fail to grow in presence of oxygen anaerobes. The jar, about 20 by Its parts are as follows:.

Gas-pak is a method used in the production of an anaerobic environment. It is used to culture bacteria which die or fail to grow in the presence of oxygen anaerobes. These are commercially available, disposable sachets containing a dry powder or pellets, which, when mixed with water and kept in an appropriately sized airtight jar, produce an atmosphere free of elemental oxygen gas O 2. They are used to produce an anaerobic culture in microbiology. These chemicals react with water to produce hydrogen and carbon dioxide along with sodium citrate C 3 H 5 O COONa 3 and water as byproducts [1]. Again, hydrogen and oxygen reacting on a catalyst like Palladiumised alumina supplied separately combine to form water. The medium , the gas-pak sachet opened and with water added and an indicator are placed in an air-tight gas jar which is incubated at the desired temperature. The indicator tells whether the environment was indeed oxygen free or not.
