BSC: Bio-Safety Cabinet
Description
- This is a completely closed cabinet, isolate operating personnel or objects to avoid damage by harmful substances, protective role.
- It is often used in high-polluting, high toxicity, high hazard job.
- Exposure to toxic chemical biology, food testing, pharmaceutical and health hazardous industries ideal for devices.
- Customized size and specification are available to meet customer's requirements.
- EN 12469 Certified (optional)
The categories of Bio Safety Cabinet are defined and classified according to the National Sanitation Foundation Standard, NSF/ANSI 49.
◎ Class I
The Class I BSC is designed to provide personnel protection
BSC grades | Inlet air velocity | % of air flow | Exhaust system | Applications | ||
m/s | internal | Exhausted | ||||
Class I | 0.38 | 0 | 100 | External | It is used for laboratories that work with | |
◎ Class II: A1, A2, B1, B2
The Class II BSC is designed not only to provide personnel protection but also to protect work surface materials from being contaminated by the room air which is drawn into the cabinet. And it is used for protecting the laboratory environment as well. It is acceptable for working with medium-level risk tests. According to the National Sanitation Foundation Standard, NSF/ANSI 49(2002), it can be defined and classified into 4 types. Their features are compared below.

Class II | 0.5 | 30 | 70 | External | It is used for laboratories which are work | |
Class II | 0.5 | 0 | 100 | |||
◎ Class III
Class III biological safety cabinets are suitable for work in Bio-safety Level 3 and 4 laboratories and provide protection for the highest hazardous level of Risk Group 3, Risk Group 4, or above. It virtually is a sealed gas-tight cabinet. Moreover, its supply air is HEPA- filtered, and exhaust air passes through two HEPA filters, which keep the cabinet interior under negative pressure consequently. The only way of accessing the work surface for operation is by means of heavy-duty rubber gloves, which are attached to ports in the cabinet virtually.
