The Fourth Day of Christmas in a Fume Extraction Wonderland

Laboratory Fume Hoods come in all shapes and sizes. There are also ductless and ducted versions.

All of the fume hoods shown in this picture are ductless, which means they don’t require exterior ducting and recirculate filtered air back into the immediate environment. You can read about the benefits of ductless systems here.
