General Lab Use: Conventional hoods found on Purdue's campus and are approved for general chemistry, radioisotopes, and carcinogen or toxic chemical work.
High Performance: These fume hoods have containment-enhancing features allowing them to operate at lower face velocities while protecting the operator. Since less room air is exhausted, energy is conserved. REM will tag high performance hoods with a special standard operating procedure sticker, informing users of the appropriate air velocity range determined by the University.
Perchloric Acid: Special hoods equipped with a stainless steel or PVC duct and properly timed water wash down system. The wash down system must be used following each use of the acid hood. Using perchloric acid in a general lab fume hood may cause the acid vapors to settle onto the ductwork and create explosive perchlorate crystals. Serious injury or fatality may result to hood users or maintenance staff if the acid crystals are exposed to vibration and detonate.
Polypropylene (Acid Resistant): Dilute acids may be used at room temperature in most fume hoods, but if you are performing acid digestion, heating, or working with concentrated acids such as: HF, Aqua Regia, Nitric Acid, Piranha Solutions, etc., acid resistant hood and ductwork is required. Strong acids are corrosive to the duct work found in general lab fume hoods. Fume hoods constructed from polypropylene material are long-lasting and designed to resist harsh chemicals for years.
Walk-In: Equipped with a floor-mounted design, walk-in hoods specialize in exhausting chemicals that are used alongside large laboratory equipment. When using a walk-in hood, close the bottom sash to the floor and only raise the top sash to REM's designated working height. Do not obstruct the area at the face of the hood.
Ductless Filtered: Designed to remove potential hazardous fumes and vapors from the work area as the exhausted air passes through absorbent material, such as activated charcoal. Occasionally, the REM department is asked to approve purchases of ductless, filtered fume hoods for use in research labs. We do not recommend ductless fume hoods. We do not believe ductless fume hoods provide reliable protection against chemical exposure, and think they may, in fact, give workers a false sense of security.
