Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.

After obtaining a sterile environment and sterile materials, we must maintain sterility in order to study or utilize the functions of a particular known microorganism, otherwise the various microorganisms outside can easily be mixed in. The phenomenon of the incompatibility of microorganisms in the outside world, we call it contaminated bacteria in microbiology. Preventing pollution is a key technology in microbiology work. On the one hand, thorough sterilization, on the other hand, prevention of contamination is two aspects of aseptic technology. In addition, we also want to prevent the microorganisms under study, especially pathogenic microorganisms or genetically engineered microorganisms that do not exist in nature, from escaping from our experimental containers to the external environment. For these purposes, there are many measures in microbiology.
The floor and walls in the sterile room must be flat, not easy to hide and dirt, and easy to clean. The table top of the workbench should be level. Ultraviolet lamps are installed in the sterile room and buffer room, and the ultraviolet light in the sterile room is 1 meter away from the work surface. Workers entering the sterile room should wear sterile clothing and wear a hat.
Currently, the sterile room is mostly found in microbiology factories, and the general laboratory uses ultra-clean benches. The main function of the clean bench is to use air laminar flow devices to remove all kinds of tiny dust including microorganisms on the upper surface of the workbench. The electric device passes the high-efficiency filter device through the electric device and enters the work surface, so that the table surface is always under the control of the flow of sterile air. Moreover, on the side close to the outside, there is a high-speed air curtain to prevent external entrained air from entering.
In places where conditions are difficult, it is also possible to replace the clean bench with a wooden aseptic box. The aseptic box has a simple structure and is easy to move. There are two holes in the front of the box. When not in operation, the push-pull door is used to block the arms. The upper part of the front is equipped with glass for easy internal operation. The inside of the box is equipped with an ultraviolet lamp, and the small door can be placed into the appliance and strains.
application:
Sterile room A very comprehensive basic supporting industry in the application industry. It is currently used in many industries such as electronic information, semiconductor, optoelectronics, precision manufacturing, medical and health, bioengineering, aerospace, automotive spraying, etc., and according to the precision of the industry. No dust requirements, the level difference is also large.
At present, the high level of Zui is an aerospace aviation aerospace warehouse, which belongs to the first level, belongs to a special field, and has a relatively small area.
In addition, the higher level requirements are biochemical laboratories and high-precision nanomaterial production workshops. The development of IoT chips will be a major direction for future demand.
With the development of electronic components in the direction of miniaturization, LCD panels have been upgraded to the eighth generation, and the industry demand is huge.
