PURPOSE:To supply gas from a tube wall to dissolve the same in a solution, in an apparatus for supplying gas to a liquid, especially, a fermentation liquid, by inserting a rod, which has a diameter smaller than the inner diameter of a gas permeable water repellent tube, through said tube. CONSTITUTION:A nozzle holder 6 is passed through the openings formed to the top plate 4 of a culture tank and a rubber plate 5, and a flange part 7 and a nozzle 8 are threaded to be fixed so as to interpose the top plate 4 and the rubber plate 5 therebetween. A tube doubled by surrounding the outer periphery of a tube 1 by an elastic tube 10 is inserted in a tube insert 11 and fixed to the lower part of the tube holder 6 by a cap nut 12 and provided with a gas leakage seal. A transverse hole 13 is provided to the nozzle holder 6 and the gas supplied from the nozzle passes the transverse hole 13 and the gap 14 between a stainless rod and the nozzle holder to be supplied into the tube. |
