Large-diameter quartz glass tubes are widely used in chemical experiments, industrial production and scientific research due to their excellent transparency, high temperature resistance and corrosion resistance. However, with the growth of use time, various stains or residues may accumulate on the inner wall of quartz glass tubes, affecting their performance and service life. Therefore, correct and effective cleaning methods are essential to maintain the performance of quartz glass tubes.

Preparation before cleaning

1. Safety protection: Before cleaning, be sure to wear personal protective equipment, such as gloves, goggles, etc., to prevent chemicals from splashing on the skin or eyes.

2. Environmental preparation: Ensure that the work area is well ventilated to avoid the accumulation of harmful gases.

3. Preparation of tools and materials: Choose the appropriate detergent (e.g. deionized water, alcohol, dilute hydrochloric acid, hydrofluoric acid, etc.) according to the type of stain, and prepare soft cloths, brushes, plastic containers, and other tools.

Cleaning steps

1. Initial flushing:

- Use a large amount of deionized water to initially rinse the inside and outside of the quartz glass tube to remove dust and loose substances from the surface.

2. Soaking treatment:

- Choose the appropriate detergent according to the nature of the stain. For organic contamination, organic solvents (such as alcohol) can be used; for inorganic salt deposition, dilute hydrochloric acid or nitric acid solutions can be used.

The quartz glass tube is completely immersed in the selected cleaning solution, and the soaking time is determined according to the severity of the stain, usually from a few hours to one night.

3. Scrub:

- For stains that are difficult to remove, you can use a soft brush to gently brush the inner wall. Be careful to move gently to avoid scratching the glass surface.

4. Ultrasonic cleaning (optional):

If conditions permit, quartz glass tubes can be placed in an ultrasonic cleaner for cleaning to further remove stubborn stains using the cavitation effect generated by ultrasound.

5. Final rinse:

After completing the above steps, rinse the quartz glass tube thoroughly with a large amount of deionized water again until the water is clear and free of impurities.

If necessary, repeat this process to ensure complete cleanliness.

6. Drying:

- Can be dried naturally or with clean compressed air. In some cases, to speed up the drying, quartz glass tubes can also be dried in a cryogenic oven.

Precautions

When handling corrosive substances such as strong acids and alkalis, it is necessary to strictly abide by laboratory safety procedures and take appropriate protective measures.

During operation, try to avoid direct contact with the quartz glass tube by hand to avoid leaving fingerprints or other oil stains.

After cleaning, all chemical reagents used should be properly disposed of in accordance with relevant regulations and should not be released at will.

Through the above steps, the stains in the large-diameter quartz glass tube can be effectively removed, its original transparency and performance can be restored, and the service life can be extended. Correct cleaning can not only ensure the accuracy of experimental data, but also improve the safety and reliability of the equipment.
