Quartz glass tube is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties,widely use in optical, chemical, semiconductor industrial, liquid crystal ,lighting, .ect. Heat resistance, light transmission, electrical insulation and chemical stability are very good.

Clear Quartz Tube

Many industries use quartz tube. These include semiconductor manufacturing, optoelectronic device production, chemical engineering, pharmaceuticals, and food processing. Quartz pipes have key uses in three fields. In semiconductor manufacturing, they use high-purity gases and liquids. This ensures a clean production environment. In optoelectronic device production, manufacturers use them to make and test optical components. In chemical engineering and pharmaceuticals, researchers use them in reactions and drug production. They have excellent corrosion resistance.

Also, quartz pipes have good light transmittance. So, they are important in optics. Manufacturers use quartz pipes to make optical parts. They also use them in lasers, fiber optics, and spectral analysis.

Advantage of Quartz Tube:

1. High purity , SiO2> 99.99%.

2. High temperature resistant.

3. Good thermal stability.

4. Acid-proof, Alkali-proof.

5. Excellent electrical insulator.

6.Good light transmittance.
