Frequently Asked Questions (FAQs)
What is a Class III Biological Safety Cabinet?
A Class III Biosafety Cabinet is a gas-tight, fully enclosed safety cabinet designed to offer maximum protection to personnel, product, and the environment when handling hazardous or highly infectious materials. All operations are conducted through attached gloves, ensuring no direct contact with the work environment.
How is a Class III BSC different from a Class II BSC?
Class III BSCs provide total containment with a gas-tight, glove box system, whereas Class II BSCs offer operator, product, and environmental protection but do not provide full containment of hazardous pathogens.
What is the purpose of negative pressure in Class III BSCs?
Negative pressure ensures that no contaminated air escapes into the lab environment, maintaining maximum safety for operators.
What industries require a Class III Biosafety Cabinet?
Virology research labs, pharmaceutical companies, military biodefense, high-security diagnostic centers, and vaccine production facilities require Class III cabinets for high-risk pathogen handling.
When should a Class III BSC be used?
Class III cabinets are ideal for:
- Handling BSL-3 and BSL-4 pathogens
- High-risk research involving viruses, bacteria, or biological toxins
- Work involving radioactive isotopes or toxic chemicals
- Pharmaceutical and API manufacturing of cytotoxic compounds
- Biodefense, vaccine production, and synthetic biology labs
How does Dyna’s Class III BSC ensure operator safety?
Dyna’s Class III Biological Safety Cabinet is designed to maintain a negative pressure environment, ensuring inward airflow at all times. Key safety features include:
- Gas-tight construction
- Dual HEPA filters for supply and exhaust
- Arm-length glove ports for sealed interaction
- Pass-through chambers for contamination-free transfer of materials
- Optional hydrogen peroxide (H₂O₂) decontamination compatibility
What is the airflow mechanism in a Class III Biological Safety Cabinet?
- Supply air is passed through a HEPA filter before entering the work zone.
- Exhaust air is filtered through two HEPA filters in series or HEPA + carbon filters when chemicals are involved.
- All contaminated air is safely ducted out through a building’s dedicated exhaust system, eliminating any risk of leakage into the room.
What makes Dyna’s Class III Biological Safety Cabinet unique?
Dyna Filters’ cabinet is engineered with:
- All-welded SS 304/316L construction for durability and cleanroom compatibility
- Rounded internal corners for easy cleaning and decontamination

- H₂O₂ fogging ports for decontamination
- This allows seamless incorporation into pharma-grade or cGMP facilities.
How are materials transferred in and out of the cabinet?
The cabinet includes an airlock or pass-through chamber equipped with interlocked doors. Materials enter and exit the cabinet without compromising containment, ensuring zero cross-contamination between external and internal environments.
Is the cabinet certified or compliant with international standards?
Yes. Dyna’s Class III Biological Safety Cabinet is designed to comply with:
- EN 12469
