📚 Frequently Asked Questions – Biosafety Cabinets

What’s the difference between Class I, II, and III biosafety cabinets?

Class I protects personnel and the environment. Class II also protects your samples, making it the most common in labs. Class III is fully enclosed and gas-tight for maximum containment in high-security labs.

Which Class II type do I need?

Type A2 is ideal for most general lab applications. Type B1 and B2 are used when working with volatile chemicals—B2 offers full exhaust for complete safety.

How often do biosafety cabinets need certification?

Biosafety cabinets should be certified at least once a year to ensure airflow, HEPA filter performance, and safety standards are being met.

Can I use a laminar flow hood instead?

No. Laminar flow hoods only protect the sample. Biosafety cabinets protect you, your lab, and your samples—required when working with biohazards.

Is a Class II cabinet good for cell culture work?

Yes. Class II cabinets are widely used for aseptic work like cell culture, microbiology, and virology because they protect both the user and the sample.

What’s the benefit of a Class III cabinet?

Class III cabinets offer maximum containment using a gas-tight design and glove ports. They're used for work with high-risk pathogens in high-containment labs.
