ABSTRACT:
A bubbler bottle has an upper chamber and a lower chamber of smaller diameter than the upper chamber. A central inlet tube extends from near the bottom of the lower chamber up through the upper chamber and the top of the bottle. An exhaust tube extends from near one side of the inlet tube laterally out through the side of the upper chamber, with its outer end adapted to be connected to a suction pump for drawing contaminated air down through the inlet tube and out of its lower end into a predetermined volume of liquid in the lower chamber. The liquid is spaced from a collar which encircles the inlet tube and is sealed to the side of the upper chamber below the exhaust tube but with clearance around the inlet tube. The capacity of the lower chamber is such that the liquid remaining in it when the bottle is on its side is beneath the inlet tube, and the capacity of the upper chamber is such that when the bottle is inverted all of the liquid in the inverted upper chamber will be below the exhaust tube. When the bottle is turned back on its side, the inner end of the exhaust tube will always be above the liquid in the upper chamber.
