Professional Laboratory Biosafety Cabinet for Safe Pathogen Handling

The Ai 2 Ft Class II Type A2 Biosafety Cabinet (BSC) is a NSF/ANSI 49 certified biological safety cabinet designed to protect laboratory personnel, research samples, and the surrounding environment when working with potentially infectious biological materials.

This Class II Type A2 biosafety cabinet provides dual HEPA filtration, controlled airflow, and sterile working conditions, making it ideal for laboratories handling COVID-19 specimens, microbiological samples, pharmaceuticals, virology research, and clinical diagnostics.

Unlike laminar flow clean benches, which exhaust unfiltered air toward the user, this biosafety cabinet uses HEPA filtration to remove harmful bacteria, viruses, and airborne contaminants before air exits the unit, ensuring both personnel safety and environmental protection.

With automatic airflow control, UV sterilization, and a motorized front glass panel, this compact 2-foot biosafety cabinet offers reliable containment in a space-saving laboratory footprint.

Key Features of the Ai Class II A2 Biosafety Cabinet

NSF Certified Biosafety Protection

Certified to NSF/ANSI Standard 49, ensuring safe containment for laboratory work involving biohazards and infectious materials.

Dual HEPA Filtration System

Two high-efficiency HEPA filters (99.995% efficiency at 0.3 μm) capture airborne contaminants before air recirculates or exhausts.

Ideal for COVID-19 and Biological Sample Handling

Provides safe containment for viral samples, microbiology research, pharmaceutical development, and clinical testing labs.

Motorized Front Glass Viewing Window

Tempered safety glass window automatically adjusts to the recommended height and can be operated with the included foot switch or remote control.

Integrated UV Sterilization System

Built-in 15W germicidal UV lamp (253.7 nm) disinfects the chamber before and after use.

Large LCD Control System

User-friendly touch control interface with remote control for easy operation, monitoring, and alerts.

Automatic Airflow Monitoring

Automatically adjusts airflow speeds while providing abnormal airflow alarms and filter replacement alerts.

Easy-to-Clean Stainless Steel Chamber

Durable 304 stainless steel interior ensures corrosion resistance and easy sanitation between experiments.

Anti-Mold & Antiseptic Housing

Special treated exterior coating prevents microbial growth on cabinet surfaces.

Removable Mobile Base Stand

Includes a detachable stand, allowing installation either on a table or as a freestanding unit.

How a Class II Biosafety Cabinet Works

A Class II Type A2 biosafety cabinet protects laboratory users and samples through controlled airflow and HEPA filtration.

Air enters the cabinet through the front opening, forming an inward airflow barrier that prevents contaminated air from escaping the workspace. Air is then filtered through HEPA filters, ensuring sterile recirculation inside the chamber.

The airflow distribution is designed so that:

• 70% of air is recirculated internally through HEPA filtration

• 30% of air is safely exhausted through the top vent

This system maintains sample sterility while preventing laboratory contamination.

Important Biosafety Cabinet Operating Procedure

Before Use

1. Fully close the front glass panel.

2. Turn on the UV sterilization light for 30 minutes.

3. Leave the room during the disinfection cycle.

4. Raise the glass panel to the recommended opening height.

5. Turn on airflow circulation for 10 minutes before beginning work.

After Use

1. Close the front glass panel.

2. Activate the UV light for another 30 minutes for decontamination.

Important Biosafety Cabinet Safety Guidelines

For safe operation, follow these guidelines:

• Do not use flammable or explosive substances inside the cabinet.

• Avoid volatile chemicals that may damage HEPA filters.

• Do not operate open flames, as they disrupt airflow patterns.

• Avoid toxic chemical vapors that may escape into the lab environment.

• Only use small volumes (≤10 mL) of disinfectants such as 70% isopropyl alcohol.

Recommended disinfectants for BSC surfaces include:

• Sodium hypochlorite (bleach)

• Iodophors (Wescodyne)

• Phenolics (Hilphene, Vespene)

• Quaternary ammonium compounds (Conflikt, Endbac II)
