ABSTRACT:
The gas inlet tube and the outlet tube in the upper end of a "bubbler" container are each sealed with an easily breakable wall adjacent the wall where the tubes join the container. A second seal is formed on the outer ends of the tubes creating a compartment in which may be positioned a small hammer. The outer seals are sufficient to meet safety regulations regarding the shipment of highly corrosive or poisonous materials. The user of the material, breaks the outer seals, positions the hammer if not already in place, makes the desired connections to the tubes, applies a purging gas to the upper ends of the tubes, and breaks the inner seals by magnetically or otherwise actuating the hammer resting on the inner seal, thereby connecting the material to the desired system without exposing the material to the atmosphere.
