Perchloric Acid Fume Hood
HSN Code: 841490
The Chromgate Perchloric Acid Fume Hood is a specialized laboratory containment system intended specifically for procedures involving perchloric acid, where appropriate hazard assessment requires a dedicated hood.
Perchloric acid applications require special consideration because potentially hazardous perchlorate residues may accumulate within the hood and exhaust system. Accordingly, these hoods require specialized construction and a dedicated wash down arrangement designed to minimize residue accumulation.

Critical Safety Requirement
A perchloric acid hood should use a dedicated exhaust system and should not be casually interconnected with conventional laboratory fume hood exhaust systems.
The complete system including the hood, wash down arrangement, ducting, blower, drainage, and discharge should be engineered according to the concentration and temperature of perchloric acid used, process conditions, risk assessment, and applicable safety requirements.
