As we all know, 2ml Glass Autosampler Vial is made of borosilicate glass. But do you the know why should select borosilicate 2ml Glass Autosampler Vial? The borosilicate glass must contain at least 5% boric oxide. Oxidized glass helps make the glass more resistant to higher temperatures and corrosion.
So when you select 2ml Glass Autosampler Vial, please confirm the raw material of 2ml autosampler vial. Type 1  borosilicate glass is the best material. Type 1 glass will provide you with the best overall performance, including lower pH shifts, temperatures above 100°C, and greater resistance to a range of substrates containing water, acids, and most organic substances.
Type 1 clear borosilicate glass has a linear expansion coefficient of 33 or 51. The linear coefficient of Type 1 amber borosilicate glass is expanded to 51. Some budget vial glass has a linear coefficient expansion of 70+. 2ml Glass Autosampler Vial is the best one.
The coefficient of thermal expansion describes how the size of an object varies with temperature. Specifically, it measures the volume change per degree of temperature change at constant pressure. There are many COES, including linearity, strain effects, area and volume. In the case of vial glass, a linear COE is the standard indicator.
