CHEMICAL SOLUTION ENCLOSING DEVICE AND CHEMICAL SOLUTION ENCLOSING METHOD
Abstract: a chemical solution enclosing device that inserts a plug into a barrel containing a chemical solution includes, a sleeve inserted into a barrel in such a manner that a tip end of the sleeve comes near a liquid surface of the chemical solution, a push rod pushing the plug inserted in the sleeve; and a suction depressurization device that draws air inside of the barrel that is isolated from outer air through a gap between an outer peripheral surface of the sleeve and an inner peripheral surface of the barrel to depressurize inside of the barrel. after the suction depressurization device depressurizes the inside of the barrel to a predetermined pressure, the push rod is advanced to push the plug from inside of the sleeve into the barrel, with a depressurized state maintained. the sleeve is withdrawn from the barrel after at least a part of an outer peripheral surface of the plug comes into fluid-tight contact with the inner peripheral surface of the barrel.
