EN7 fume hoods, designed for special applications with high thermal loads and/or exposure to acids, must meet extremely demanding requirements in accordance with DIN EN 14175-7. In specific models, we have, among other things, adapted the airflow design to ensure a laminar flow and safe extraction even when working with high heat sources (e.g. hot plates). The use of a special application fume hood and appropriate materials also makes it possible to work with perchloric acid and hydrofluoric acid.
