Custom high borosilicate glass tube Transparent Pyrex tube sight glass for industrial use

‌High borosilicate glass tube ‌ is a kind of high performance scientific research experimental glass tube, specially designed to meet a variety of scientific research and industrial needs, its main components are silica and boron oxide, with excellent heat resistance, chemical corrosion resistance and optical transparency ‌.

High borosilicate glass (also known as hard glass), because of the linear thermal expansion coefficient of (3.3 0.1)×10-6/K, it is also called "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, process jewelry and other industries. Its good performance has been widely recognized by all walks of life in the world, especially in the field of solar energy is more widely used, Germany, the United States and other developed countries have been more widely promoted.

Features:

1. Low coefficient of thermal expansion: the coefficient of thermal expansion of high borosilicate glass is (32.5±0.5)×10^-7/℃, and the volume change is small when the temperature changes, and it can withstand a large temperature difference and is not easy to break.

2. High temperature resistance: high borosilicate glass contains high silica (SiO2) and boron oxide (B2O3), so that it can remain stable at temperatures as high as 820℃.

3. Chemical stability: High borosilicate glass has good resistance to most chemicals, especially acid substances, showing excellent corrosion resistance.

4. Light transmittance: As a transparent material, high borosilicate glass has good light transmittance, which is suitable for optical instruments and application scenarios requiring light transmittance.

5. Mechanical strength: Although high borosilicate glass itself is more fragile, but its mechanical strength and toughness are high, suitable for making thin-walled but durable glass products.

6. Electrical conductivity: At high temperatures, high borosilicate glass has electrical conductivity, which gives it an advantage in some special applications.

7. Biocompatibility: High borosilicate glass has good biocompatibility and low toxicity, and is widely used in biomedical devices and drug packaging.

8. Low dielectric constant: high borosilicate glass has a low dielectric constant, suitable for semiconductor devices and display devices.
