Protector PVC Perchloric Acid Laboratory Hoods feature washdown systems, integral work surfaces and drainage troughs so that they may be thoroughly rinsed after each use to prevent the accumulation of potentially reactive perchloric salts. Their liners of Type 1 unplasticized polyvinyl chloride are designed to withstand reaction from perchloric acid.
Protector PVC Acid Digestion Laboratory Hoods feature Lexan* polycarbonate sashes, which are recommended for applications involving the use of acids including hydrofluoric acid but not perchloric acid. The Lexan material does not fog or etch when exposed to hydrofluoric fumes.
These benchtop hoods are available in 4, 6 and 8-foot widths. They feature heat-welded unplasticized PVC liners, built-in washdown systems, integral work surfaces and drainage troughs.
