Procedures and precautions for using clean workbench
Note: The service life of clean bench is related to the cleanliness of the air. In temperate regions, clean bench can be used in general laboratories. However, in tropical or subtropical areas where the atmosphere contains a lot of pollen or dust, the ultra-clean table should be placed in a better room with two doors.

Under any circumstances, the air inlet cover of the ultra-clean table should not face the open door or window, so as not to affect the service life of the filter screen. Ultraviolet lamps can also be hung on the ultra-clean workbench, but they should be installed outside the lighting lampshade, and the arrangement of the lighting lamps should be staggered, so as not to hinder the lighting when working.

Never put the ultraviolet lamp into the lighting lampshade (glass plate), because ultraviolet rays cannot penetrate the glass, and its lamp tube is timely glass, not silicate glass.

Second, the use of clean workbench program:

1, when using the workbench, first wipe the countertop with gauze soaked in cleaning solution, and then wipe it with disinfectant;

2. Turn on the power supply, turn on the ultraviolet lamp 50 minutes in advance to irradiate and disinfect, and treat and purify the microorganisms accumulated on the surface of the workbench in the work area. After 30 minutes, turn off the ultraviolet lamp and turn on the blower;

3. Don't store unnecessary items on the workbench, and keep the clean airflow in the work area undisturbed;

4. After the operation, clean the workbench, collect all wastes, turn off the fan and lighting switch, and wipe and disinfect with detergent and disinfectant;

5. Finally, turn on the ultraviolet lamp of the workbench, and after irradiation and disinfection for 30 minutes, turn off the ultraviolet lamp and cut off the power supply;

6. Measure the average wind speed in the working area with an anemometer every February. If it is found that it does not meet the technical standards, adjust the handle of the voltage regulator and change the input voltage of the fan to make the workbench in the best state;

7, a monthly maintenance inspection, and fill in the maintenance records.

Extended data:

1. clean bench, also known as clean bench, is designed to meet the requirements of modern industry, photoelectric industry, biopharmaceuticals, scientific research and experiments for the cleanliness of local working areas.

It sucks air into the pre-filter through the fan, enters the high-efficiency filter through the static pressure box for filtration, and sends the filtered air out in the state of vertical or horizontal airflow, so that the operating area can reach a hundred-level cleanliness and ensure the requirements of environmental cleanliness in production.

Second, the principle of clean workbench:

In a specific space, indoor air is first filtered by a pre-filter, then pressed into a static pressure box by a small centrifugal fan, and then filtered by an air high efficiency filter. The clean airflow blown from the air outlet surface of the air high efficiency filter has a certain and uniform cross-sectional wind speed, which can eliminate the original air in the working area and take away dust particles and biological particles, thus forming a sterile and highly clean working environment.

Third, the clean workbench uses:

It is a one-way air purification equipment, which can provide a local dust-free and sterile working environment. It is suitable for scientific research and production departments that need local clean and sterile working environment, such as medical and health, biopharmaceuticals, food, medical science experiments, optics, electronics, sterile room experiments, sterile microorganism inspection, plant tissue culture and inoculation.

It can also be connected into an assembly line with the characteristics of low noise and mobility. Its use has a good effect on improving process conditions, improving product quality and increasing output.
