VA4000 Series cabinets are Vertical or Horizontal Unidirectional Airflow Benches, and are designed to provide sterile working environments to protect biological material being manipulated from contamination. Unidirectional Airflow Benches protect the sample from the operator but not the operator from the sample. Pre-filtered air passing through the main HEPA filter ensures sterile unidirectional airflow over the work surface.
