  • Patent number: 6302786
    Abstract: A vented laboratory cabinet from which vapors and fumes may be effectively exhausted from all parts of the cabinet includes an interior storage space defined by a plurality of panels that are accessible through a closeable door, at least one shelf carried within the cabinet interior, and a vent pipe extending downwardly from an exhaust opening toward a lower part of the cabinet. Improved venting is achieved with a vent pipe having at least two vertically spaced apart vent openings for passage of gases from the cabinet into the vent pipe, wherein at least one of the vent openings is located above the shelf and at least one other vent opening is located below the shelf. The improved vented laboratory cabinet provides effective evacuation of fumes from both sides of the shelf, whereby accumulation of chemical vapors is reduced or eliminated.
