Industries: Healthcare, Biocontainment, Biopharma
USP <800> Compliant
- All Stainless Steel Construction
- 70% Recirculated / 30% Exhausted HEPA Filtered Air
- ISO 5 / Class 100 Laminar Flow Air in the Work Area
- Optional Transition Piece for External Ducting
Protection for Operators, Products, and the Environment
A Class II, Type A2 biosafety cabinet recirculates approximately 70% of HEPA-filtered air and exhausts the rest, protecting the product, operator, and environment simultaneously.
The Class 2, Type A2 Laminar Flow Biosafety Cabinet provides a high degree of localized protection from particulate and aerosol hazards. The work area is continuously bathed with laminar flow ISO 5 HEPA-filtered air to protect the product from contamination, while an inward airflow protects the user. About 70% of the air from each cycle is recirculated through the supply HEPA filter, and the rest is discharged through the exhaust HEPA filter. These cabinets are built to eliminate cross-contamination and the accidental release of carcinogenic aerosols and drugs to the outside environment.
All-stainless-steel construction holds up under the wide range of cleaning chemicals laboratory and cleanroom use demands, giving these cabinets a long service life.
Suitability
Designed to meet the needs of multiple applications, the Class II Type A2 Biological Safety Cabinet (BSC) is ideal for a wide range of industries and facilities.

Frequently Asked Questions
What is a Class 2, Type A2 biosafety cabinet?
A Class 2, Type A2 biosafety cabinet (BSC) is a laminar flow enclosure that uses ISO 5 HEPA-filtered air to protect the product, operator, and environment simultaneously. It recirculates approximately 70% of filtered air back into the work area and exhausts the remaining 30% through a dedicated exhaust HEPA filter.
How does a Type A2 BSC protect against cross-contamination?
Inward airflow at the cabinet opening prevents contaminants from escaping into the room, while continuous ISO 5 HEPA-filtered laminar flow across the work surface protects the product from outside contamination. The exhaust HEPA filter captures any hazardous aerosols before air is released, preventing accidental release of carcinogenic aerosols or drugs to the environment.
What is the difference between a Type A2 and Type B2 biosafety cabinet?
A Type A2 cabinet recirculates roughly 70% of its air within the cabinet and exhausts the rest, while a Type B2 cabinet exhausts 100% of its air with no recirculation. Type B2 cabinets are typically required when working with volatile chemicals or toxic vapors that shouldn’t be recirculated at all, while Type A2 cabinets suit most biological work.
What is a Class 2, Type A2 BSC used for?
Class 2, Type A2 biosafety cabinets support applications including 503B outsourcing, aseptic filling, cell and gene therapy, viral vector production, CRISPR research, monoclonal antibodies (mAbs), mRNA and plasmid production, radiopharmaceuticals, vaccine development, antibody-drug conjugates, hazardous drug handling, and analytical testing, across mobile, modular, and cGMP facility platforms.
What is the cabinet constructed from?
All Germfree Class 2, Type A2 biosafety cabinets are built with all-stainless-steel construction, designed to withstand the wide range of cleaning chemicals required in laboratory and cleanroom environments for a long service life.
