Labconco and Kewaunee, manufacturers of laboratory hoods, produce ADA compliant products for use by individuals with disabilities. The base cabinets and work surfaces are available at heights appropriate for wheelchair access. The ADA fume hoods have the electrical receptacles and light switch lower, near the apron. The gas, water, and air fixtures are lower on the frame of the hood and the sink cut out is in the front of the hood. The biosafety cabinets have all controls near the lower part of the cabinet. With the addition of an adjustable base stand (either manual or electric) the working height can be adjusted for the comfort of the scientist.
