Lab Class II Type A2 Biological Safety Cabinet

Our Class II Type A2 Biological Safety Cabinet (BSC) is engineered for biosafety level 2 (BSL-2) applications, combining personnel, product, and environmental protection in one compact, efficient unit. Measuring 1100×750×2250 mm, it operates with 30% exhaust / 70% recirculation​ (Type A2 mode) and supports optional 100% exhaust​ (Type B2 configuration) for enhanced containment flexibility. Certified to meet NSF/ANSI 49, EN 12469, and WHO standards, it achieves Class 100 cleanliness​ with ≥99.995% filtration efficiency on 0.3 μm particles, making it ideal for clinical diagnostics, life sciences, and pharmaceutical research where contamination control is non-negotiable.

Constructed with seamless 304# stainless steel interiors, double-laminated explosion-proof glass, and smart digital controls, this BSC delivers reliable performance, ergonomic comfort, and simplified maintenance—perfect for modern laboratories demanding both safety and productivity.

• Personnel Protection: Impact sampler ≤10 CFU/time · Slit sampler ≤5 CFU/time
• Product Protection: Colony count ≤5 CFU/time
