Therefore, these experiments were conducted in the oven of a gas chromatograph at temperatures of 60 and 100°C and times ranging from 2 h to 4 days. Two‐gram samples were placed into 8 mL ashed borosilie glass vials with 5 mL of degassed ultrapure‐deionized water and thoroughly mixed using a spatula cleaned with DCM and MeOH.

Borosilie glass is superior. The coefficient of soda-lime glass is more than double that of borosilie glass, meaning it expands more than twice as fast when exposed to heat and will break very quickly.Borosilie glass has a much higher proportion of silicon dioxide in comparison to regular soda lime glass (80% vs. 69%), which makes it even less susceptible to fractures.
Unless otherwise noted, 1 L DURAN®, borosilie glass bottles with Teflon‐lined caps were filled with 1 L of water, leaving a headspace volume of about 100 mL. One chlorine or chlorine dioxide water purifiion tablet was added and dissolved by repeated shaking.
Worldwide Glass offers vials and inserts made from the following materialsAny silie glass containing at least 5% of boric oxide is called Borosilie Glass. The boric oxide makes the glass resistant to extreme temperatures and chemical corrosion. Type I borosilie has the least pH shift of any glass
