Bio Safety Cabinet (BSC) ClassII A2

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

Features

Selection of a biological safety cabinet (BSC)

BSC category	Laboratory type	Type of protection
Class I	Groups 1–3, microorganisms in Risk; Slightly volatile, radionuclide/chemical protection	Operator, environment
Class Ⅱ A1	Groups 1–3, microorganisms in Risk	Operator, environment, product
Class Ⅱ A2	Groups 1–3, microorganisms in Risk	Operator, environment, product
Class Ⅱ B1	Groups 1–3, microorganisms in Risk; Slightly volatile radionuclide/chemical protection	Operator, environment, product
Class Ⅱ B2	Groups 1–3, microorganisms in Risk; Minute amounts volatile, radionuclide/chemical protection	Operator, environment, product
Class III	Groups 1–3, microorganisms in Risk; Volatile, radionuclide/chemical protection	Operator, environment, product

The categories of Bio Safety Cabinet are defined and classified according to the National Sanitation Foundation Standard, NSF/ANSI 49.

- The Class I BSC is designed primarily for the protection of operating personnel
BSC grades	Inlet air velocity	% of air flow		Exhaust system	Applications
	m/s	internal re-circulated	Exhausted
Class I	0.38	0	100	External (hard duct)	It is used for laboratories which are work with nonvolatile, radionuclide/chemical protection, microorganisms in Risk.

- 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. And according to the National Sanitation Foundation Standard, NSF/ANSI 49(2002), it can be defined and classified as 4 types. Their features are compared as below.

- Class III biological safety cabinets are suitable for work in Bio-safety Level 3 and 4 laboratories and provide the protection for the highest hazardous level of the 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 to the work surface for operation is by means of heavy duty rubber gloves, which are attached to ports in the cabinet virtually.
BSC grade	Inlet air velocity	% of air flow		Exhaust system	Applications
	m/s	internal re-circulated	Exhausted
Class III	N/A	0	100	Exhaust air should pass through two filters.	It is used for laboratories which are work with lightly volatile, toxic, radionuclide protection, microorganisms in Risk.
