In addition, take a look at the superiority of the boro glass:
This is the unique material that is used in precise laboratory equipment known for its durability, heat resistance and lightweight. It has very low coefficient of thermal expansion, which makes borosilicate glass much stronger than traditionally made glass.
Borosilicate glass has the ability to be exposed to two different temperatures at the same time from −20oC to +130oC (for safety reasons it is highly recommended that temperature difference does not exceed 150oC)
