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 |
