Perchloric Fume Hood

Perchloric Fume Hood

A perchloric acid fume hood has similar characteristics of standard bench top fume hood; however, interior lining and work surface must be made of SS 304 which are coved and seamlessly welded. Non-reactive and corrosion resistant material must be used through out the exhaust system. Perchloric acid fume hood will have to have water wash down system to remove perchlorates and prevent building-up potentially explosive perchlorate salts. A work surface has in-built open drain trench at rear side of hood under the baffle. The drain outlet should have capacity to drain minimum of 56.8 litres per minute. Perchloric fume hood system should not be clustered for common exhaust system.
