No additives 100% floral water pure water "must be sterile"




After obtaining a sterile environment and sterile materials, we have to maintain a sterile state in order to conduct research on certain known microorganisms or use their functions, otherwise various microorganisms from the outside are easily mixed. The phenomenon of the mixing of unrelated microorganisms from the outside world is called contaminating bacteria in microbiology. Prevention of pollution is a very critical technology in microbiology work. On the one hand, thorough sterilization, on the other hand, prevention of contamination, are two aspects of aseptic technology. In addition, we have to prevent the microorganisms under study, especially pathogenic microorganisms or microorganisms that have been genetically engineered 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 of the aseptic room must be flat, not easy to hide dirt and easy to clean. The surface of the workbench should be level. The sterile room and buffer room are equipped with ultraviolet lamps, and the ultraviolet lamp in the sterile room is 1 meter away from the work surface. Workers entering the sterile room should wear sterilized clothing and hats. 
Currently, aseptic rooms are mostly found in microbial factories, while general laboratories use ultra-clean benches. The main function of the ultra-clean table is to use the air laminar flow device to remove all kinds of tiny dust including microorganisms on the work surface. The electric device allows air to enter the work surface after passing through the high-efficiency filter device, so that the work surface is always kept under the control of flowing sterile air. In addition, there is a high-speed air curtain on the side close to the outside to prevent the entry of outside air with bacteria.
In places with more difficult conditions, a wooden sterile box can also be used instead of the ultra-clean table. The aseptic box has a simple structure and is easy to move. There are two holes on the front of the box, which can be blocked by a small push-pull door when not in operation, and arms can be extended in during operation. The upper part of the front is equipped with glass, which is convenient for internal operation. The inside of the box is equipped with ultraviolet lamps, and utensils and bacteria can be put in from the side door.
