Laminar Flow Cabinet vs Biosafety Cabinet: What's the Difference?
Published by Australian Mycology Equipment
One of the Most Common Questions We Receive
Many people use the terms laminar flow cabinet and biosafety cabinet interchangeably, but they are designed for very different purposes.
Choosing the wrong cabinet can compromise both your work and your safety.
This guide explains the differences between laminar flow cabinets and biosafety cabinets, helping you choose the right equipment for your laboratory.
What Is a Laminar Flow Cabinet?
A laminar flow cabinet provides a continuous stream of HEPA-filtered air across the work surface.
The filtered air removes airborne particles, helping protect samples from contamination while creating an ultra-clean workspace.
Laminar flow cabinets are designed to protect the product being worked on, not the operator.
They are commonly used for:
- Mycology
- Tissue culture
- Electronics assembly
- Pharmaceutical preparation
- Media preparation
- Sterile laboratory procedures
How Does It Work?
Air passes through a HEPA filter before flowing smoothly across the work surface in one direction.
This constant airflow removes airborne dust and microorganisms that could contaminate sensitive samples.
Because the airflow is directed toward the operator, hazardous chemicals or infectious materials should never be used inside a standard laminar flow cabinet.
What Is a Biosafety Cabinet?
A biosafety cabinet is designed to protect:
- The operator
- The laboratory environment
- The sample
Instead of simply providing clean air, biosafety cabinets contain potentially hazardous biological materials using carefully controlled airflow and exhaust filtration.
These cabinets are commonly used in:
- Hospital laboratories
- Clinical microbiology
- Virology
- Medical research
- Public health laboratories
The Main Differences
| Laminar Flow Cabinet | Biosafety Cabinet |
|---|---|
| Protects the sample | Protects the sample, operator and environment |
| Horizontal or vertical clean airflow | Controlled containment airflow |
| Air flows toward the operator | Air is safely contained and filtered |
| For non-hazardous work | For biological hazards |
| Simpler design | More complex safety systems |
| Lower cost | Higher cost |
Which One Do You Need?
If your goal is simply to keep your work free from airborne contamination, a laminar flow cabinet is usually the right choice.
Typical applications include:
- Mushroom culture
- Plant tissue culture
- Electronics assembly
- Optical equipment
- Laboratory sample preparation
If you're handling infectious agents or hazardous biological materials, a certified biosafety cabinet is required.
HEPA Filters Are the Key
Both types of cabinet rely on high-efficiency HEPA filters.
A genuine H14 HEPA filter captures at least 99.995% of airborne particles at the most penetrating particle size, making it suitable for demanding laboratory environments.
Regular filter replacement helps maintain clean airflow and reliable performance.
Choosing the Right Size
When selecting a laminar flow cabinet, consider:
- Bench space
- Sample size
- Number of operators
- Future laboratory growth
- Available power supply
Buying a cabinet that's slightly larger than your current requirements often provides greater flexibility in the future.
Why Australian Laboratories Choose Local Suppliers
Purchasing from an Australian supplier offers several advantages:
- Australian warranty
- Local technical support
- Faster delivery
- Readily available spare parts
- Expert advice before purchase
These benefits help minimise downtime and provide peace of mind throughout the life of your equipment.

Final Thoughts
Understanding the difference between a laminar flow cabinet and a biosafety cabinet is essential before making a purchase.
For laboratories requiring a clean, particle-free working environment, a laminar flow cabinet offers excellent protection for sensitive samples. However, if your work involves hazardous biological materials, a biosafety cabinet is the appropriate and safer choice.
Choosing the correct equipment ensures better results, improved laboratory safety and long-term reliability.
