Class II Bio Safety Cabinets From Kewaunee

Interceptor Bio Safety Cabinet

Designed to focus on user protection, these Class II Interceptor BSCs feature state-of-the-art advancements that enhance overall lab operations. By combining cutting-edge technology with a secure working environment, Kewaunee BSCs allow scientists to concentrate fully on their research without compromising peace of mind or convenience.

Interceptor A2/B2 BSC Variants

  • Class II Type A2 Biosafety Cabinets
  • The Class II Type A2 Biosafety Cabinet is the most widely utilized model among all Class II BSCs. It efficiently operates with a minimum inflow of 100 FPM (0.5 meters per second), ensuring a safe working environment. This cabinet combines HEPA-filtered downflow with recycled air to provide maximum protection. Additionally, it offers versatility in exhaust options, allowing either partial or total recirculation of HEPA-filtered air back into the laboratory.

  • Class II B2 Biosafety Cabinets
  • A Class II Type B2, biological safety cabinet is specifically engineered to eliminate internal air recirculation. Due to its non-recirculation feature, the Type B2 biosafety cabinet is an ideal solution for tasks involving toxic chemicals and microbiological processes. The cabinet maintains a minimum inflow rate of 100 FPM (0.5 m/s), ensuring optimal contamination control. The air is HEPA filtered, both in its downflow and exhaust, safeguarding the external atmosphere from potential contaminants.


The Science Behind Safety: How Biosafety Cabinets Work?

Biosafety cabinets provide robust protection against laboratory contamination through their advanced design and precision-engineered airflow systems, creating a meticulously controlled environment

Here are the primary methods through which biosafety cabinets operate to prevent contamination:


The Bio safety cabinet employs high-efficiency particulate air (HEPA) filters to intake surrounding air, meticulously filtering contaminants. This purified air is circulated downward within the cabinet, ensuring any potential hazards are contained. Depending on the cabinet design, the filtered air can be either recirculated or exhausted.


Biosafety cabinets are equipped with a front-facing sash crafted from transparent material, usually glass. This design element is a vital physical barrier, protecting researchers from direct contact with hazardous substances.


The inward airflow in biosafety cabinets ensures that contaminants do not escape into the laboratory environment. This design feature guarantees that any biological or chemical agents handled within the cabinet remain securely contained, preventing their dispersion into the surrounding air.


HEPA filters employed in biological safety cabinets effectively capture particles as minuscule as 0.3 microns with remarkable efficiency, meticulously removing airborne contaminants from the airflow before they enter the laboratory workspace.

Kewaunee is a leading manufacturer of ergonomic and environmentally friendly Class II biosafety cabinets (BSCs). Utilizing advanced HEPA filters and laminar airflow technology, our BSCs ensure personnel, products, and environmental protection from hazardous biological materials. The downflow air in our BSCs passes through High-Efficiency Particulate Air (HEPA) filters to prevent biohazard exposure and cross-contamination risks.

Our state-of-the-art biosafety cabinet provides maximum protection against hazardous exposures while enabling users to maintain strict control over product quality. Kewaunee's offerings include NSF/ANSI 49 and UL 61010-1 Underwriters Laboratories-certified Class II BSC models.
