Lab Class II Type A2 Biological Safety Cabinet

Lab Class II Type A2 Biological Safety Cabinet
Product Overview

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.
