Quartz glass tube, as a high-performance material, has a wide range of applications in optical instruments, laboratory equipment, industrial production, and other fields due to its high transparency, corrosion resistance, and high temperature resistance. To ensure the selection of quartz glass tubes that meet the requirements, the following selection criteria can be considered:

1、 Material selection

The material of quartz glass tube is the primary consideration when choosing. High quality quartz glass has high transparency, corrosion resistance, and high temperature resistance. When selecting, it should be ensured that the SiO2 content of the quartz glass tube reaches 99.9% or more to ensure its excellent chemical and thermal stability.

2、 Specification and size

Diameter and length: Choose the appropriate diameter and length of the quartz glass tube according to actual application requirements. For example, the diameter range of transparent quartz tubes is usually 1.5~160mm, and the length can reach 10~3000mm. Quartz sleeves have a wider diameter range, typically between 8-120mm.

Wall thickness: The wall thickness of quartz glass tubes is also a factor that needs to be considered, as it directly affects the strength and high temperature resistance of quartz tubes. The wall thickness range of transparent quartz tubes is usually between 0.5 and 15mm.

3、 Optical performance

Quartz glass tubes have good transparency in the entire spectral range from ultraviolet to infrared, with a visible light transmittance of over 93%. Especially in the ultraviolet spectral region, the maximum transmittance can reach over 80%. Therefore, when purchasing, attention should be paid to the optical transmittance of quartz glass tubes to ensure that they meet application requirements.

4、 Surface quality

Pores: High quality quartz glass tubes should have no pores on the surface, as the presence of pores can affect the sealing and service life of the quartz tube.

Scratches: Quartz tubes with deep and obvious surface scratches are considered non-conforming products. When making a purchase, you can gently scratch the surface of the quartz tube with a key or pencil sharpener to check for any obvious scratches.

Collapse crack: Quartz tubes with open fracture cracks are also considered unqualified products. When purchasing, carefully check the upper and lower edges of the cut surface of the quartz tube to ensure that there is no cracking phenomenon.

5、 Processing and Customization

Precision: High precision quartz glass tubes can ensure good sealing and installation convenience. When selecting, attention should be paid to the dimensional accuracy of the quartz tube to ensure that it meets the application requirements.

Surface treatment: Good surface treatment can enhance the corrosion resistance, wear resistance, and high temperature resistance of quartz glass tubes. Common surface treatments include expansion, contraction, flanging, sanding, etc.

Customization: Quartz glass tubes with different diameters, lengths, and surface treatments can be customized according to actual needs. Customized quartz glass tubes can better meet specific application needs.

6、 Environmental Protection and Safety

When choosing quartz glass tubes, attention should be paid to their environmental friendliness and safety. High quality quartz glass tubes should be produced using environmentally friendly materials, with no residual harmful substances such as formaldehyde. At the same time, quartz glass tubes should be used to ensure that they do not pose any harm to human health and the environment.

When selecting quartz glass tubes, multiple factors need to be considered, including material, specifications, optical performance, surface quality, processing and customization, environmental protection and safety, as well as brand and supplier. By considering these factors comprehensively, high-quality quartz glass tubes that meet the needs can be selected.
