中硼。
以下摘自USP660
Glass used for pharmaceutical containers is either borosilicate
(neutral) glass or soda-lime-silica glass. Borosilicate glass contains significant amounts
of boric oxide, aluminum oxide, and alkali and/or alkaline earth oxides. Borosilicate glass
has a high hydrolytic resistance and a high thermal shock resistance due to the chemical
composition of the glass itself; it is classified as Type I glass。
我这里的是USP31的,660 CONTAINERS—GLASS。怎么感觉是高硼硅玻璃啊!
