Borosilicate glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability has made it the glass of choice for high-end restaurants, laboratories, bars, and wineries.

All of our clear glass vials are made using type 1, 33-expansion glass. Type 1, 51-Expansion Glass More alkaline than type 1, 33-expansion glass, type 1, 51-expansion glass, is nonetheless adequate for use in many laboratories. Composed primarily of silicone and oxygen, with trace amounts of boron, its expansion coefficient is 51 × 10 –7 ˚C
expansion glass gave the largest shift. In Figure 1 vials made of different glass types have been compared. Figure 1 In general results were as expected, with Chromacol™ GOLD Grade™ vials exhibiting best results and 70 expansion glass the worst. One result of note is the very similar performance of EU 51 expansion glass and US 33 expansion
