How to clean alumina tube

1. Begin by vacuuming the outside of the tube to remove any debris or dust. 

2. Use a mild detergent and scrub the tube with a soft cloth or brush.

3. Use a mild abrasive or a toothbrush to scrub the inside of the tube.

4. Rinse the inside and outside of the tube with warm water and a soft cloth. 

5. Use a clean, lint-free cloth to dry it.



Quality testing standards

1. Visual inspection of the tube for any signs of damage or irregularities.

2. Measurement of the length, width, and thickness of the tube to check for accuracy.
3. Confirmation that the end of the tube is properly sealed.
4. Checking for any leaks or pinhole defects in the tube.
5. Testing for proper adhesion of the end cap to the tube.
6. Verification of the material and chemical composition of the tube.
