Ultra-clean workbench operation principle and precautions
Working principle The air is sucked into the pre-filter by the fan, and the high-efficiency filter is filtered through the static pressure box, and the filtered air is sent out in a state of vertical or horizontal airflow, so that the operation area reaches 100-level cleanliness, and the production is clean. Requirements. The ultra-clean workbench is divided into a vertical flow ultra-clean workbench and a horizontal flow ultra-clean workbench according to the direction of the airflow. According to the operation structure, it is divided into two types: unilateral operation and bilateral operation. According to its application, it can be divided into ordinary super-clean work. Taiwan and biological (medicine) ultra-clean workbench.
Operating specifications:
1. Check the operating environment of the ultra-clean workbench such as ambient temperature, air quality, power supply, etc., and register the use information;
2. Place the equipment required for the experiment on the surface of the ultra-clean workbench, put the material that has been sterilized, such as the culture medium, on the left side, and place the tool on the right side;
3. Pull down the glass baffle and turn on the UV lamp for 30 minutes for surface sterilization;
4. After 30 minutes, turn off the UV lamp, turn on the fan to adjust to the appropriate air volume, and turn on the light;
5, open the glass baffle to about 20cm high, both hands can be operated smoothly in the console, wipe the hands and countertops with 75% alcohol;
6. Ignite the alcohol lamp, and the operation process strictly follows the aseptic operation specification;
7. After the operation is completed, clean the experimental equipment out of the aseptic table, 75% alcohol to wipe the table, turn off the lighting, fan and baffle.
8. Turn off the UV lamp after turning on the UV lamp for 15 minutes.
Precautions:
1. It is strictly forbidden to store items for a long time in the ultra-clean workbench;
2. Ultraviolet rays are highly irritating to the skin and retina, avoiding direct ultraviolet rays, and single-layer glass can effectively block ultraviolet rays;
3. The operation process should strictly abide by the aseptic operation specifications;
4. Avoid frequent switching of UV lamps and lighting tubes to extend the service life of the lamps;
5, regularly check the air filter and other filter materials, aging should be replaced.

The fundamental difference from traditional electric scooters, battery scooters, bicycles and other transportation tools is that electric wheelchairs have intelligent operating controllers. According to the different operation methods, there are rocker-type controllers, and controllers controlled by various switches such as the head or blowing system. The latter is mainly suitable for severely disabled people with upper and lower limbs. Nowadays, electric wheelchairs have become an indispensable means of transportation for the elderly and the disabled. It is suitable for a wide range of objects.
