Portable Biosafety Cabinet: A Complete Guide by Global Lab Supply

In today’s rapidly evolving scientific landscape, the need for portable biosafety cabinets (BSCs) has never been more apparent. These versatile pieces of equipment play a crucial role in protecting both laboratory personnel and the environment while working with hazardous biological materials. Global Lab Supply, a leading provider of laboratory equipment and supplies, is here to guide you through everything you need to know about portable biosafety cabinets.

Understanding Portable Biosafety Cabinets

What is a Portable Biosafety Cabinet?

A portable biosafety cabinet is a specialized piece of laboratory equipment designed to provide a safe and controlled environment for working with biological materials, including bacteria, viruses, and other potentially hazardous substances. Unlike traditional BSCs, portable BSCs can be easily moved between different locations within a laboratory or even between laboratories.

Why Choose a Portable BSC?

Portable biosafety cabinets offer several advantages, including:

  • Flexibility: Their mobility allows researchers to work with hazardous materials in various lab settings.
  • Cost-Efficiency: They eliminate the need to purchase multiple fixed BSCs for different labs.
  • Space Optimization: Laboratories with limited space can benefit from their compact design.
  • Easy Relocation: They can be transported to different facilities or labs as needed.
  • Compliance: They meet biosafety standards and regulations for containment.

Types of Portable Biosafety Cabinets

Class I Portable BSC

Class I portable biosafety cabinets provide operator and environmental protection. These cabinets direct airflow away from the user, ensuring that contaminants are contained within the cabinet. However, they do not provide product protection, making them suitable for low-risk applications.

Class II Portable BSC

Class II portable biosafety cabinets are the most common choice in laboratories. They provide operator, environmental, and product protection. There are two subtypes:

  • Type A1: Recirculating BSCs with a minimum of 70% air recirculated through a HEPA filter.
  • Type A2: Recirculating BSCs with a minimum of 70% air recirculated through a HEPA filter, and a portion of the exhaust air is discharged outside the laboratory.

Class III Portable BSC

Class III portable biosafety cabinets are designed for maximum containment and are often used when handling the most hazardous biological materials, such as Ebola virus or anthrax. Operators work inside a glove box, and all materials are passed through airtight ports, ensuring no release of pathogens.

Selecting the Right Portable BSC

Application Considerations

When choosing a portable biosafety cabinet, consider the following factors:

  • The type of biological materials you will be working with.
  • The required containment level (BSL-1 to BSL-4).
  • The available laboratory space.
  • The need for mobility within the lab.
  • Budget constraints.

Compliance and Certification

Ensure that the portable BSC meets the relevant regulatory standards and certifications, such as NSF/ANSI 49 and EN 12469. These certifications ensure that the cabinet provides the specified level of protection.

Ergonomics and User Comfort

The ergonomic design of the cabinet is essential for the comfort and safety of the operator. Look for features like adjustable height, armrests, and easy-to-use controls.

Installation and Maintenance


Proper installation of a portable biosafety cabinet is crucial for its performance. Follow the manufacturer’s guidelines and consider factors like airflow, clearance, and electrical requirements.


Regular maintenance is essential to ensure the continued effectiveness of your portable BSC. Tasks may include:

  • Routine filter replacement: HEPA filters should be replaced at least annually.
  • Leak testing: Conduct regular tests to ensure the cabinet’s integrity.
  • Certification: Periodic certification by trained professionals is necessary to verify compliance.

Safe Operation

Preparing for Use

Before using a portable biosafety cabinet, make sure to:

  • Perform a visual inspection to check for any visible damage.
  • Verify that airflow indicators are functioning correctly.
  • Check that the cabinet is properly certified and has up-to-date filters.

Personal Protective Equipment (PPE)

Always wear appropriate PPE when working with hazardous materials inside a BSC. This may include lab coats, gloves, safety glasses, and face shields.

Work Practices

Follow good laboratory practices when working with hazardous materials, including:

  • Minimizing movement inside the cabinet to avoid disrupting airflow.
  • Avoiding clutter to maintain optimal airflow.
  • Using aseptic techniques when handling materials.

Troubleshooting Common Issues

Loss of Airflow

If you notice a loss of airflow or reduced containment, it may be due to:

  • Clogged filters: Replace the HEPA filters as recommended by the manufacturer.
  • Damaged seals: Check and replace damaged gaskets or seals.
  • Obstructed vents: Ensure that vents are not blocked.

Unusual Noises

Unusual noises can indicate problems with the cabinet’s motor or fan. If you hear unusual sounds, contact the manufacturer or a service technician for inspection and repairs.

Filter Replacement

Improper filter replacement can compromise containment. Always follow the manufacturer’s guidelines for filter replacement, and consider scheduling regular filter replacement as part of your maintenance routine.

Safety and Regulatory Compliance

Biosafety Levels (BSL)

Understanding the biosafety level required for your work is critical. Ensure that your portable BSC meets the containment requirements for the specific biological materials you handle, whether it’s BSL-1, BSL-2, or higher.

Regulatory Compliance

Portable biosafety cabinets must comply with international standards and regulations, such as NSF/ANSI 49 or EN 12469. Regular certification and testing help maintain compliance and ensure safety.

Training and Documentation

Proper training of personnel is essential for safe operation. Keep thorough documentation of training records and maintenance schedules to demonstrate compliance with regulatory requirements.

Future Trends and Innovations

Advanced Filtration Technology

Ongoing advancements in filtration technology are improving the efficiency and safety of portable BSCs. Look out for innovations in filter materials, air handling systems, and energy efficiency.

Smart Cabinets

The integration of smart technology is making it easier to monitor and control portable BSCs remotely. These systems can provide real-time data on airflow, filter status, and maintenance needs, enhancing safety and efficiency.

Sustainable Design

Sustainability is becoming a key consideration in laboratory equipment design. Manufacturers are developing portable BSCs with energy-efficient features and materials that reduce their environmental impact.


Portable biosafety cabinets are indispensable tools in modern laboratories, offering flexibility, safety, and compliance with regulatory standards. Global Lab Supply has provided you with a comprehensive guide to understanding, selecting, and maintaining these essential pieces of equipment. By following best practices and staying up-to-date with innovations, you can ensure the safe and effective operation of your portable biosafety cabinet in your laboratory.
