Identify the quality of quartz tube can be from the following aspects:

1. Appearance check:

   - Check whether the surface of the quartz  tube is smooth, no bubbles, sand, cracks, scratches and other defects.

   - Observe the uniformity of the wall, a good quartz tube wall should be uniform, without obvious uneven thickness.

2. Transparency:

   - High-quality quartz tube should have a high degree of transparency, through the light should not be obvious color or turbidity.

3. Dimensional accuracy:

   - Use vernier calipers or other measuring tools to check whether the inner and outer diameters, wall thickness and other dimensions of the quartz tube meet the specifications.

4. heat resistance:

   - Quartz tube should have good heat resistance. It can be tested by heating test to see whether it is deformed or ruptured at a certain temperature.

5. chemical stability:

   - Quartz tube should have good chemical stability, not easy to react with chemical reagents. It can be examined by immersion test to check its performance in specific chemical reagents.

6. Physical performance test:

   - Perform pressure resistance test to check whether it will leak or rupture under specified pressure.

   - Perform bending strength test to check its resistance to bending.

   - Perform thermal shock tests to check its resistance to cracking under rapid temperature changes.

7. Brand and manufacturer:

   - Choose well-known brands and manufacturers with good reputation who usually provide quality assurance and good after-sales service.

8. Relevant certificates and reports:

   - Check whether the product has relevant quality certificates, such as SGS certification, third-party test reports, etc.

9. Price comparison:

   - Price is often proportional to quality, too low price may mean poor quality.

10. user reviews:

- Learn about other users' reviews and usage experience, which can be used as a reference.

When buying quartz tubes, it is recommended to communicate with the supplier in detail to clarify your usage needs so that you can choose the right product. If conditions permit, it is better to take samples for testing to ensure that the selected quartz tube meets the specific application requirements.
