Fume hood

A fume hood or fume cupboard is a large piece of scientific equipment common to chemistry laboratories designed to limit a person's exposure to hazardous fumes. Fume hoods were originally manufactured from timber, but now epoxy coated mild steel is the main construction material. Two main types of unit exist, ducted and recirculating. With the ducted type, old asbestos vent pipe has been superseded on health grounds, typically with PVC or polypropylene. The principle is the same for all units; air is drawn in from the front of the cabinet by a fan, and expelled either outside the building, or made safe through filtration and fed back into the room.

Epoxy: Epoxy or polyepoxide is a thermosetting epoxide polymer that cures when mixed with a catalyzing agent or "hardener". Most common epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A. The first commercial attempts to prepare resins from epichlorohydrin occurred in 1927 i...
