Perchloric Acid Fume Hoods — Wash-Down Systems for Safe Digestion
Perchloric acid creates explosive perchlorates when vapors contact organic materials or accumulate in ductwork. Perchloric acid fume hoods prevent this through stainless steel construction (no organic materials), integral wash-down systems that rinse the interior and ductwork after each use, and dedicated exhaust systems with stainless steel ductwork.
Labs USA supplies perchloric acid hoods with 316 stainless steel liners, integral water spray systems, stainless steel work surfaces, and dedicated exhaust fans. These hoods must be installed on independent exhaust systems — never combined with general laboratory exhaust.
Frequently Asked Questions
Why can’t I use a regular fume hood for perchloric acid?
Perchloric acid vapors react with organic materials (epoxy coatings, PVC ductwork, lubricants) to form explosive perchlorates that accumulate in ductwork joints and fans. Regular hoods use organic materials and share ductwork — creating explosion and fire hazards. Perchloric hoods eliminate these risks through all-stainless construction and wash-down systems.
How often should perchloric acid hoods be washed down?
After every use of perchloric acid — even small quantities. The wash-down cycle takes 5–15 minutes and rinses all interior surfaces and ductwork. Many facilities also perform monthly wash-downs regardless of use as a preventive measure.
