Abstract

A bubbler ampoule and bubbler assembly for containing highly corrosive chemicals is configured so as to provide enhanced strength which allows safe transport and usage of high vapor pressure chemicals. The enhanced assembly strength is provided by controlling the ratio of the bottom wall thickness to the side wall thickness of the ampoule; and by providing properly radiused corners on the ampoule.
