An ampoule holder receives a glass ampoule with a collar surrounding the ampoule neck to permit smooth breaking away of the ampoule tip at the collar. A stopper is inserted into the ampoule mouth and a bubbler tube is then inserted through the stopper and mouth into the interior of the ampoule to form a tight seal between the stopper and ampoule. A slit extending through the insertion portion of the stopper forms a vent passage for air flowed into the ampoule through the tube. The connection between the stopper and ampoule forms an integral ampoule assembly with the collar confined between the stopper and ampoule. The assembly may be placed in apparatus for conducting an optical analysis of liquid in the ampoule.
