How should the air shower transfer window in the laboratory be safely operated? 

How should the air shower transfer window in the laboratory be safely operated? 

    The air shower transfer window is one of the common purification equipment in the laboratory. It is used to maintain a clean environment and ensure the safety of the experimental process. To ensure the normal operation of the air shower transfer window and the safety of users, we need to pay attention to the following safety operating matters when using the air shower transfer window.

1. Keep the transfer window clean

    First, we need to keep the delivery window clean. Before starting the equipment, the internal and external surfaces of the transfer window and the ventilation ducts should be cleaned to effectively reduce the accumulation of dust and microorganisms and ensure the accuracy of experimental operations and the reliability of results.

2. Pay attention to operating specifications

    Before using the air shower transfer window, you should carefully read the operating instructions and safety tips to understand how to use the transfer window and follow the correct operating procedures to avoid misoperation.

(1) When we open the transfer window, we should push the metal handle lightly to ensure that the door is fully open.

(2) During the process of transferring experimental supplies, the door of the transfer window should be kept open, and the number of times that arms and hands are put into the transfer window should be minimized.

(3) After the operation is completed, the door of the transfer window should be closed in time to prevent contaminants from entering the inside of the transfer window.

3. Regular inspection

    Regularly check pass-through window filters and ventilation systems to ensure they are functioning properly. Regularly replace filters, clean ventilation ducts, and maintain and maintain equipment to ensure the normal use of the transfer window. If the filter is found to be clogged or the ventilation system fails, it should be repaired and replaced in time to avoid affecting the experimental process and results.

4. Sensitive response

    In addition, the air shower transfer window also has a sensitive infrared sensor door. Users need to be close to the door to trigger the signal to open the door, ensuring a safe distance between the person and the window.

5. It is prohibited to intercept the door

    Users are not allowed to block obstacles, loiter, or take selfies when using the air shower transfer window, so as not to affect the use of other people or cause the transfer window to malfunction.

6. Use valuables with caution

    When passing valuables, it is recommended that users use the air-shower passing window with a completely clear line of sight, and place the items in the center of the passing port to prevent collisions or items from being broken.

7. It is prohibited to receive unknown items

    If unknown items are found when receiving items, they should be reported to relevant personnel immediately for verification. It is strictly prohibited to receive items from unknown sources to prevent safety accidents.

8. Direct contact with the window is prohibited

    Never touch the surface of the transfer window directly with your hands, feet, or other objects to avoid damaging the protective film of the window or the internal transfer device.

9. Personal hygiene

    The safe operation of the air shower transfer window also includes the personal hygiene of the experimenters.

(1) When using the transfer window, experimenters should wear clean lab coats, gloves, masks, and other protective gear to avoid contaminating experimental samples and equipment.

(2) At the same time, experimenters should wash their hands frequently to keep their hands clean and avoid contacting pollutants with the surface of the transfer window.

    In summary, the safe operation of the air shower transfer window is the key to ensuring the safety and accuracy of the experimental process. Correct use of the transfer window, compliance with operating specifications, regular maintenance of equipment, and attention to personal hygiene can effectively protect experimental samples and experimenters and ensure the reliability and accuracy of experimental results.
