ABSTRACT:
An apparatus for dissolving a gas, such as oxygen, into a liquid, such as water, having a low concentration of that gas. The apparatus has an inlet, an outlet and a central region therebetween and has walls defining an interior adapted for dissolving the gas in the liquid. The apparatus also has a gas injecting means adapted for maximizing a gas-liquid interface and promoting contact between the gas and the liquid, thereby maximizing the concentration of the gas in the liquid. The apparatus is useful for modifying the liquid for a specific purpose, such as for developing a culture medium. The apparatus can have different internal configurations, depending on the degree of gas linkage and retention required.
