美国VWR生物安全柜 II-B2型号

Labculture* Class II Type B2 Biosafety Cabinets, Esco Technologies

This cabinet provides optimum operator, product, and environmental protection in experiments involving general microbiological work with agents assigned to CDC biological safety levels 1, 2, or 3. Ideal for situations where recirculation of filtered air is prohibited, usually due to the presence of chemical fumes emitted during the process.

Sentinel l* Silver microprocessor monitors airflow in real-time via temperature compensated sensors. Minipleat ULPA (Ultra Low Penetration Air) filter operates at a typical efficiency of 99.999% for 0.1–0.3µm particles, surpassing conventional HEPA (High Efficiency Particulate Air) filters. The ULPA filter provides ISO Class 3 (FED-STD-209E Class 1/M1.5) clean air to the work surface in a gentle vertical laminar flow. An integral filter metal guard prevents accidental damage to the filter media. A seamless filter gasket is permanently molded on the filter frame and will not deteriorate over time. Typical main ULPA filter lifespan is more than five to seven years depending on the usage of the cabinet.
