The Biobase FH1000(A) and (E) Series are full-sized, ducted fume hoods engineered for heavy-duty laboratory use where large volumes of toxic or corrosive vapors must be safely exhausted. These hoods are constructed with a robust cold-rolled steel exterior and a high-grade, chemical-resistant interior liner. The (A) series features a traditional design with comprehensive safety interlocks, while the (E) series offers enhanced ergonomic features and updated microprocessor controls for more precise airflow management. Both models include a motorized front sash made of tempered glass, integrated water and gas taps, and a chemical-resistant worktop. They are designed for connection to a building’s HVAC or a dedicated external fan, ensuring that all hazardous byproducts are completely removed from the laboratory environment. These “workhorse” fume hoods provide the essential protection required for high-traffic chemical research, pharmaceutical development, and industrial testing facilities.
