Fume cupboards, also known as laboratory chemical hoods, fume hoods, fume cabinets or film filtration cabinets are large pieces of scientific equipment very common in chemical, biological and medical laboratories. They are fume extraction systems designed to protect researchers in from toxic fumes.
Lab hoods were invented over one hundred years to protect scientists and lab workers who needed to handle hazardous materials.
Over the years, there have been many refinements to the original Victorian design, but the basic concept of laboratory hoods remains the same.
Fume hoods were originally made from wood, but now epoxy coated mild steel is the favoured main construction material.
