Of the hundreds of commercial glasses produced, PYREX low expansion borosilicate Type I glasses comes closest to being the ideal glass for most laboratory applications.

With proper care, they will withstand nearly all temperatures used in normal laboratory use. They are highly resistant to chemical attack. Their low coefficient of expansion allows them to be manufactured with heavy walls, giving them mechanical strength, while retaining good heat resistance.
