A clean bench is a type of environment control equipment specially used for production, processing, and experiments. It ensures that the air quality on the surface of the workbench reaches a high level of cleanliness to prevent external contaminants from entering the work area, ensuring product quality and the accuracy of experimental results. The following points should be noted when using a clean bench:

1. Wear appropriate protective equipment: When operating a clean bench, appropriate protective equipment should be worn, including gloves, masks, and lab coats, to prevent personnel from contaminating products due to improper operation.

2. Keep the workbench surface clean: When using a clean bench, the workbench surface needs to be kept clean to prevent dust, debris, etc., from entering the work area, affecting work efficiency and the accuracy of experimental results.

3. Regularly check the filters: The filter of the clean bench is the key equipment to ensure clean air quality. The filter needs to be regularly checked and replaced to ensure its normal operation and prevent air quality from declining due to filter failure.

4. Avoid storing food or drinks on the clean bench: To avoid bacteria and other impurities being brought in by food and drinks, food or drinks should be avoided on the clean bench to ensure the cleanliness of the workbench.

5. Avoid irrelevant operations on the clean bench: The clean bench is a special device used for production, processing, and experiments. Irrelevant operations should be avoided on the workbench to prevent external contaminants from entering the work area, affecting product quality and the accuracy of experimental results.

6. Regularly clean and disinfect the workbench: To maintain the cleanliness of the clean bench, the workbench needs to be regularly cleaned and disinfected to prevent the growth of bacteria and other contaminants, affecting work efficiency and product quality.

7. Strictly abide by the operating procedures: When using a clean bench, the operating procedures must be strictly followed, and operations must be performed according to the operating instructions to ensure the normal operation of the workbench and product quality.

In short, a clean bench is a special device used for production, processing, and experiments, and users need to strictly observe...
