Recently encountered a problem in knowing
Can I use a biosafety cabinet instead of a clean bench? Can it be completely replaced in addition to price and cost?The comment area begins to discuss, everyone has their own views
Today, it is emphasized that the working principle and use of biological safety cabinets and ultra-clean work platforms are different, and the two cannot be mixed! So don't think that the two can replace each other. 
The main differences between biosafety cabinets and ultra clean benches:
1. Biosafety cabinet is a kind of safe, clean equipment used in the fields of biomedicine, microbiology, biological products, etc., and applied in the production process. Colleagues are also one of the biosafety in the laboratory. The most basic safety protection device in the level protection screen.
2. The biosafety cabinet is a kind of negative pressure purification workbench. It is a bio-safety isolation device, which protects the staff and working environment from biological bacteria and protects the life safety of the operator and the safety of the working environment. The ultra-clean workbench protects not the staff and the working environment but the operating objects. Therefore, in the fields of microbiology, biomedicine and other fields, research, teaching and production use biosafety cabinets instead of ultra-clean workbench.
3. The ultra-clean workbench is designed as a material for protecting the laboratory. The air is sucked into the pre-filter through the fan, and the high-efficiency filter is filtered through the static pressure box to filter the filtered air in a vertical or horizontal airflow state. This enables the operating area to achieve 100 levels of cleanliness to ensure the cleanliness of the work area, but to protect the sample from protecting personnel.
4. In terms of cleanliness, the biosafety cabinet is higher than the clean bench. The advantage of the ultra-clean workbench is that the operation is relatively simple.
The two can't be mixed! ! ! Important thing plus three exclamation points
