Feature
●Diameter 180mm/7.09in
●Environmental friendly lead-free borosilicate glass is the best material for making a watch borosilicate glass, which is reusable, non-toxic, and easy to clean
●High temperature resistance, the expansion coefficient is only one third of ordinary glass, annealing point 560℃, linear coefficient of expansion 32×10-7/℃, softening point 820℃
●They not only can be used for vaporizing liquid, but also can be used as a lid for other chemical containers
●Place the chemicals to be observed,but also cover the beaker to slow the evaporation of the contents and prevent dust from entering
