Class II B2 Biological Safety Cabinet Airstream B2, 99.999% ULPA Filtration (CAT#: STEM-AL2-5916-ZJF)

The Class II B2 Biological Safety Cabinet Airstream B2 is designed for Class II B2 containment of biological work involving volatile chemicals or radionuclides. It uses controlled airflow and filtered air handling to reduce the release of aerosols during laboratory work. The cabinet architecture supports simultaneous protection of personnel, samples, and the surrounding environment as described for the configuration. High-efficiency filtration and the stated clean-air performance maintain controlled conditions in the work zone. Integrated monitoring supervises airflow, pressure, sash position, or related operating parameters according to the source configuration. Alarm and interlock functions alert the operator when monitored conditions move outside the intended operating state. The work area uses cleanable construction and source-specified antimicrobial, stainless-steel, or negative-pressure features for routine containment work. The system is intended for containment-oriented biological handling within the applications described in the source.
