ABSTRACT:
A funnel (20) for use in dumping volatile solvents into an underlying carboy (16) is ecologically friendly in that it blocks solvent from evaporating from the carboy into the atmosphere. The funnel has (a) an extended stem (22), the bottom open end of which is below the surface of the solvent (18) in the carboy to reduce surface evaporation, (b) an occluder or obturating ball (24) in the throat of the funnel to block evaporation through the stem of the funnel, and (c) a lid (28) on the funnel to block evaporation. The ball may be float operated, with or without a captivating cage (26), or it may be operated by lifting the lid, which may be performed manually or via a foot pedal (38).
