PYREX® Crystallizing Dish, made of Borosilicate Glass 7740, is an ideal glass for laboratory use and is temperature and chemical resistant. The glass adheres to the ASTM E438 Standard Specification for Glasses in Laboratory Apparatus. The reinforced rims reduce chipping and other imperfections, manufactured with heavy walls made possible by the glass having a low coefficient of expansion. This coefficient makes the glass extremely durable, with a thermal shock resistance of up to 160°C for 3.2 mm thick dishes. The glass also withstands high temperatures, with a thermal stress resistance of up to 54°C.
Pyrex dishes withstand sterilization (wet or dry) and are perfect for storage and crystallization.
