We all know that a clean workbench is a commonly used purification equipment in laboratories, do you know? According to different usage environments and categories, the cleanliness level of clean workbenches is generally divided into three categories. The following are the detailed contents:

　　According to international standards, it can generally be divided into levels 100, 1000, and 10000

　　The 100 level clean workbench, also known as the A level workbench, has a cleanliness level of no more than 3.5 particles with a diameter greater than 0.5 micrometers per cubic foot, and the number of bacteria in the air per cubic foot cannot exceed 1000;

　　A clean worktable of level 1000 is level B, with a cleanliness level of no more than 35 particles with a diameter greater than 0.5 microns per cubic foot, and no more than 10000 bacteria in the air per cubic foot;

　　A clean workbench of level 10000 is level C, with a cleanliness level of no more than 350 particles with a diameter greater than 0.5 microns per cubic foot, and no more than 100000 bacteria in the air per cubic foot;

　　2. According to different usage scenarios and needs, ultra clean tables are generally divided into three levels: A, B, and C, mainly based on air cleanliness and microbial cleanliness.

　　3. In addition, there is also a concept called "high-risk operation area", in which a specific environmental state needs to be maintained. This type of clean workbench used is relatively special and of the highest level, for example, some specific steps in the production process of sterile drugs need to be carried out within it.

　　The above is the relevant content on how to classify the cleanliness level of a clean workbench. We hope it is helpful to you. If you want to learn more about this content, you can visit the official website of Haisiyuan at www.hsy515.cn!
