NSF 49 vs EN 12469 — Biosafety Cabinet Standards Compared

Two standards, one goal

NSF/ANSI 49 and NF EN 12469 both define the design, construction and performance requirements for Class II biosafety cabinets. NSF 49 is the North American reference; EN 12469 is the European one. Both ensure operator, product and environmental protection.

Key differences

The standards differ in test methods, airflow velocity requirements and certification procedures. A cabinet designed to meet both — as ADS Laminaire cabinets are — is suitable for US laboratories while satisfying international expectations.

Which applies to you

In the United States, NSF 49 is the expected reference for Class II biosafety cabinets. Explore our biosafety cabinets designed to comply with both standards.
