The Iroquois perchloric acid hood is designed specifically for procedures using perchloric acid. Based on our LA-series superstructure, it features a one-piece, cove-cornered Type 316 stainless steel interior with integral work surface and washdown system. Regular use of the washdown system cleanses the hood interior of peroxidizable compounds, which drain into a full-length sloped trough contained in the work surface. Access to plumbing is through exterior access panels only.


Due to the extreme reactivity of perchloric acid, this hood should be used for perchloric acid ONLY

Standard features include:
  • One-piece Type 316 stainless steel interior – 16-gage coved corners welded to 14-gage, dished, reinforced countertop with integral cupsink and full-length sloped trough; all surfaces are polished to #4 finish
  • High-volume washdown tube with remote control cold water valve
  • Two-piece Type 316 stainless steel baffle system with adjustable upper and lower dampers to regulate lighter- and heavier-than-air gases
  • Airfoil around full perimeter of sash opening, with electrical fixtures and plumbing controls mounted on bias surface
  • Side post electrical and plumbing knockouts in standard or ADA configuration
  • Bypass grill with adjustable louvers to control bypass air volume
  • Full frame, Type 316 stainless steel vertical sash with integral stainless steel finger pull
