What are the steps for using a clean workbench?

    The clean workbench is a kind of local air purification equipment, suitable for clean room workshops, sterile rooms, and other working environments. It is mainly used in medical and health, biopharmaceutical, biological laboratories, industrial laboratories, and other related industries. The box body is made of a 1.2-thick high-quality cold-rolled steel plate treated with electrostatic spraying (or stainless steel), a stainless steel work surface, high-quality centrifugal fan, available in single-sided and double-sided models.

    The following steps are a routine operation process that can be appropriately adjusted and improved according to the actual situation and experimental requirements.

    1. First, thoroughly disinfect the equipment and tools that need to be used, such as instruments, tools, bacterial bags, test tubes, etc., and put them into a clean workbench. Ensure cleanliness and sanitary conditions of the work environment.

    2. Before using the clean workbench, press the power button 30 minutes in advance to turn on the machine, check the relevant parameter settings and the working status of the equipment, and then turn on the ultraviolet lamp to treat microorganisms on the surface of the operating area to ensure a sterile environment in the work area.

    3. Before leaving the room where the ultra-clean workbench is located, turn on the ultraviolet lights in the buffer rooms one by one for disinfection. After disinfection is completed, turn off the instrument for 30 minutes to allow ozone to convert into oxygen to avoid irritation to the operator.

    4. Then press the fluorescent light button to turn on the fluorescent lamp and start the fan to start the operation. Ensure the safety and comfort of staff.

    5. Staff should wear disposable masks, hats, and medical latex gloves during operations to prevent cross-infection and contamination.

    6. During the required operation, open the sliding door of the clean workbench appropriately and conduct experiments by the aseptic operating procedures. Ensure the accuracy and reliability of the experimental process.

    7. After work, use 75% alcohol to wipe and purify the work surface, turn off the air blower, turn on the UV lamp for 15 minutes of disinfection, and then turn off the power. Keep work surfaces clean and safe.

    8. After use is completed, fill in the use record for subsequent reference and traceability. Ensure work standardization and record integrity.

Before performing any operation, you must pay attention to the following matters:

    1. It is strictly prohibited to place irrelevant objects in the ultra-clean work area to ensure that the flow of clean air is not disrupted.

    2. For new or long-term unused workbenchs, it is necessary to use a vacuum cleaner with an ultra-static function or a tool that does not produce fibers for cleaning. Carefully clean the work surface and surrounding mirrors and disinfect or use ultraviolet sterilization.

    3. The operating temperature in the operating area cannot exceed 60°C.

    4. In addition, the equipment should be cleaned regularly. Cleaning work should include routine cleaning and regular maintenance before and after use. When fumigating, be sure to completely seal all gaps. For clean bench types with removable baffle lids, plastic film can be used for sealing.

    5. The filter plate and ultraviolet germicidal lamp of the clean workbench have marked service life and must be replaced on time. Only workbenches that have passed third-party clean bench testing and are qualified can better protect samples.

    6. In addition, we should also pay attention to the use of different ultraviolet disinfection lamps to avoid the resistance of bacteria to ultraviolet light.

    7. Make sure the cleanliness of your workbench is not just about the surface, but also about the internal components to ensure they function properly. If any malfunction or abnormal condition is found, stop using it immediately and carry out repairs.

    8. Regularly evaluate and update workbench usage guidelines and train operators to follow correct operating procedures. This ensures long-term efficient operation of the workbench and provides optimal sample protection.

    In short, the operating steps and precautions for a clean workbench are of great significance to ensure the cleanliness of the working environment and the accuracy of experimental operations. Only by taking appropriate operating and protective measures can we ensure the reliability and accuracy of experimental results and protect the health and safety of operators. Therefore, we should strictly follow the operating procedures and regularly maintain and maintain the clean workbench to ensure its normal use and durability of excellent results.
