Excellent thermal shock resistance
Its low thermal expansion reduces stress during heating and cooling, lowering the risk of cracking when temperatures change.

Material
Key performance reasons technical buyers choose borosilicate 3.3 tubing for laboratory, industrial, and process applications.

Its low thermal expansion reduces stress during heating and cooling, lowering the risk of cracking when temperatures change.

It withstands elevated temperatures, making it suitable for heated laboratory equipment and industrial processes. The allowable operating temperature depends on the application and tube design.

It resists water, many acids, salt solutions, and organic solvents. Important exceptions include hydrofluoric acid, hot concentrated phosphoric acid, and strong alkaline solutions.

Its transparency allows operators to observe liquid levels, flow, color changes, and reactions directly through the tube.

Its resistance to heat, water, and chemicals supports repeated cleaning and sterilization, making it useful for reusable laboratory and process equipment.

It can be cut, bent, fire-polished, and joined to manufacture laboratory glassware, sight tubes, and custom glass assemblies.
