Class 2 Biosafety Cabinets – Vital for Lab Safety and Biological Containment
Maintaining a safe lab environment is crucial in today’s advanced research and clinical setups. Whether it's conducting biological tests, diagnostics, or experiments with infectious agents, biosafety cabinets are central to preventing cross-contamination and safeguarding personnel.
Among the available options, Class 2 Biosafety Cabinets stand out for their balanced protection. These units are crucial for working with moderate-risk organisms and sensitive samples.
Biosafety Cabinets – How They Work and Why They Matter
Biosafety cabinets are ventilated enclosures built to protect both users and biological materials. They use high-efficiency filters to purify air entering and leaving the cabinet.
These units are generally classified into three categories—Class I, Class II, and Class III. Among these, Class 2 cabinets are the most versatile and commonly used.
Defining Class 2 Biosafety Cabinets and Their Role
Class 2 Biosafety Cabinets are designed to safeguard three aspects: the operator, the sample, and the environment. They generate a vertical airflow that reduces turbulence and contamination.
Contaminated air is drawn into the cabinet and filtered through HEPA systems before recirculation or exhaust. These cabinets are ideal for work involving moderate-risk pathogens (BSL-2/3).
Essential Features of Class 2 Safety Cabinets
A Class 2 microbiological safety cabinet includes several critical technologies such as:
• High-efficiency air filters to ensure clean workspace air
• Steady air movement to reduce airborne particle circulation
• Pressure differentials that maintain internal containment
• Optional UV lights for overnight sterilisation
• Low sound emissions to reduce fatigue
• Clear front panel for visibility and safety
These elements create a clean, contained, and user-friendly workspace.
Where Class 2 Cabinets Are Used
Class 2 Biosafety Cabinets are commonly used across microbiology, biotechnology, diagnostics, and pharma. They are critical for DNA/RNA extraction, pathogen culture, and molecular assays.
Whether in hospitals or drug manufacturing, these units are essential for clean procedures.
Why Laboratories Prefer Class II Safety Cabinets
Using Class 2 cabinets offers numerous benefits for safety, accuracy, and lab hygiene:
• Reduces the risk of sample cross-contamination and error
• Shields operators from harmful aerosols and pathogens
• Improves environmental safety by filtering outgoing air
These cabinets support biosafety goals while improving lab productivity.
Cabinet Types and Global Compliance
Top manufacturers ensure their cabinets meet certifications like NSF 49, EN 12469, and WHO recommendations. Class 2 units are sub-classified as A1, A2, B1, and B2—each with distinct airflow and exhaust features.
• Type A2: Most commonly used cabinet model
• Type B2: Used for hazardous vapors and chemicals
Matching the cabinet type to your process is essential.
How to Select a Class 2 Safety Cabinet
Before purchasing, consider:
• Your application type (e.g., diagnostics, pharma, research)
• Cabinet dimensions, ducting needs, and room layout
• Operational costs and technical support options
• Service network and part availability
Partnering with a trusted provider helps meet both performance and safety needs.
Safe Setup and Operation of Class 2 Cabinets
For optimal results:
• Minimise airflow interference during operation
• Schedule regular performance checks
• Ensure operators follow best practices
Operational best practices include:
• Maintain biosafety gear protocols
• Work calmly to prevent airflow disturbances
• Wipe work areas with disinfectants regularly
• Use UV microbiological safety cabinet lights only when cabinet is off and unoccupied
Why Class 2 Cabinets Are a Must-Have in Labs
Class 2 biosafety cabinets are essential for labs that value safety, precision, and cleanliness. They safeguard both research outcomes and operator health.
From clinical research to vaccine development, Class II cabinets support world-class laboratory practices. When investing in a biosafety cabinet, opt for trusted brands that offer end-to-end service—because safe science starts with smart containment.
