GUIDELINES FOR AUTOSAMPLER VIAL SELECTION The lower the coefficient of expansion the better the glass can handle vials are often used for ion chromatography because of the extremely low metal.

Type I Borosilicate Glass - calpaclab.com

The common type of borosilicate glass used for laboratory glassware has a very low thermal expansion coefficient (3.3 x 10−6/K), [5] about one-third that of ordinary soda-lime glass. This reduces material stresses caused by temperature gradients which makes borosilicate a more suitable type of glass for certain applications.

The importance of chemical composition for vial performance

The ideal chemical composition of a glass vial. Perhaps the key metric in determining the suitability and analytical performance of a vial is the linear COE (coefficient of expansion). COE is a standardized measure of the fractional change in size per degree change in temperature at a constant pressure.
