Why are most of the chemical instruments made from glass?
Of course, the glass is colorless and transparent is also very important, the front of some people said that the glass is cheap, I would like to deny, in fact, this glass is not often in general glass, high temperature, the cost is much higher than that
The raw materials of glass equipment, especially now with the more conventional glass GG_17 and 95 of the original material, are high borosilicate glass, the internal structure of the glass with good stability, high physical and chemical properties, because the expansion coefficient is low, so it can better withstand high temperature difference, has chemical stability good performance
Because experiments require high temperatures, heating, freezing, and many complex processes of chemical reactions,
