Product Description

Borosilicate Tubular Gauge Glass Tube

Borosilicate Glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glass is known for having very low coefficients of thermal expansion (3.3 × 10?6 K?1 at 20 °C), making them more resistant to thermal shock than any other common glass.

Borosilicate glass tube, which is also known as tubular gauge glass, pyrex glass tube. is usually used in tubular level gauge for high temperature and pressure resistance, and it is also a leading material for laboratories, industry and architecture because of its strength, versatility, resistance and vast

range of dimensions for a variety of worldwide applications.
