The ultra clean workbench (clean workbench) is designed to meet the requirements of modern industry, optoelectronic industry, biopharmaceutical industry, scientific research, and experimentation for the cleanliness of local work areas.
Note: The ultra clean workbench (clean workbench) is different from the biosafety cabinet (biosafety cabinet).
The ultra clean workbench can only protect the reagents operated in the workbench from contamination, but cannot protect the staff; The biosafety cabinet is a negative pressure system that can effectively protect workers.
The working principle of the ultra clean workbench is: air is sucked into the pre filter through a fan, and then filtered by a high-efficiency filter through a static pressure box. The filtered air is sent out in a vertical or horizontal airflow state, ensuring that the operating area reaches a hundred level of cleanliness and meeting the environmental cleanliness requirements of production.
The ultra clean workbench can be divided into vertical flow ultra clean workbench and horizontal flow ultra clean workbench according to the airflow direction.
The ultra clean workbench can be divided into unilateral operation and bilateral operation according to the operation structure, and can be divided into ordinary ultra clean workbench and biological (pharmaceutical) ultra clean workbench according to the purpose.
The ultra clean workbench is a purification workbench used in fields such as healthcare, pharmaceuticals, and chemical experiments, providing a sterile, dust-free, and clean environment.
When it comes to ultra clean workstations, some people may ask, is it the same as a biosafety cabinet?
In fact, the characteristics of the ultra clean workbench are sterile, dust-free, and clean, which can protect the reagents operated in the workbench from contamination.
The biosafety cabinet is designed to protect the operator, laboratory environment, and experimental materials from exposure to infectious aerosols and splashes, which may occur during the operation of infectious experimental materials such as primary cultures, bacterial strains, and diagnostic samples. Outstanding safety and effective protection of staff.
The main differences between the ultra clean workbench and the biosafety cabinet are as follows:
1. Biosafety cabinet is a safety equipment widely used in scientific research, teaching, clinical testing, and production in fields such as microbiology, biomedicine, gene recombination, animal experiments, and biological products. It is also the most basic safety protection equipment in the primary protective barrier of laboratory biosafety.
2. The ultra clean workbench aims to protect experimental materials. The air is sucked into the pre filter through a fan, and enters the high-efficiency filter through a static pressure box for filtration. The filtered air is sent out in a vertical or horizontal airflow state, ensuring that the operating area reaches a cleanliness level of 100 and meeting the environmental cleanliness requirements of production. Only the sample can be protected, not the operator.
3. The biosafety cabinet is a negative pressure purification workbench. When the biosafety cabinet is properly operated, it can protect workers and test samples, and prevent cross contamination. The ultra clean workbench is just a clean workbench, protecting the operating objects rather than the staff and laboratory environment.
Therefore, in the research, teaching, clinical testing, and production of microbiology and biomedicine, biosafety cabinets should be used instead of ultra clean workstations.
4. In terms of cleanliness level, the biosafety cabinet is also superior to the ultra clean workbench.
