Clean room is widely used in bacteria test room and purification room. Nanjing Expansion Technology has more than ten years of design experience. Laboratory purification engineering, aseptic laboratory engineering, laboratory ventilation system engineering are relatively high requirements for enterprises, experimental samples are relatively sensitive to the environment. Or if the air quality is too poor, it will pollute the experimental samples, such as biological products, microbiological research, brain cell laboratory, stem cell laboratory, blood cell laboratory, animal laboratory, biosafety laboratory, virus research laboratory and so on, it will be necessary to require the laboratory or some areas of the laboratory air purification Treatment of chemical engineering system. In order to ensure that the laboratory's infrastructure meets the requirements of the experiment, the experiment is carried out safely.

Laboratory purification engineering is not only to protect the safety of experimental samples, but also to protect the success of the experiment and the safety of laboratory personnel. Laboratory purification project is to open up a certain area of the laboratory, specially used to build a clean air level, relatively high laboratory environment requirements or sterile room. The laboratory purification engineering system is very different from the traditional clean room system, but the pressure, microbial control and temperature and humidity control in the clean room are more stringent than those in the industrial clean room. Common laboratory cleaning engineering decoration materials are sandwich color steel plate, tempered glass, fire prevention board, etc., clean laboratory must be in accordance with the "clean room construction and acceptance standards" can be better sealed and dust-free materials for partition, ceiling decoration, clean laboratory ventilation system is generally used in combination with air conditioning unit The difference between the air supply system and the clean room engineering is that not all laboratories can have a return air system, depending on the use of the user laboratory and the experimental products. Similar to biosafety laboratories, it is not possible to do a return air system, or to use a full-exhaust cleanroom approach to the construction.

The grade design of laboratory purification engineering is also very important. The general cleanliness grade of aseptic room laboratory is ten thousand, while the general laboratory is a layout design of one hundred thousand to ten thousand. The biosafety laboratory, positive control laboratory and microbial culture laboratory should be designed and constructed according to the static 100-grade clean room standard.
