A pipe coupling comprises a tubular casing and a sealing gasket, which fit over the ends of the pipes to be coupled. The apparatus includes a cathode, an extraction electrode, a lens electrode, an anode, deflectors, electron lenses, and a detector. The premeasured compressed charge has a leading end portion and a trailing end portion and the leading end portion is either the same size or a smaller dimension than the trailing end portion. The receptacle folds out to form a cup during use and the cup is positioned at a height lower than the rim of the toilet fixture thereby enabling urination by a person that is too short to reach the rim of the toilet fixture. The reactions are preferably carried out in a manner that minimizes rearrangement of the reaction product. The device inserts into the existing molded pull cup on a vehicle’s door panel.
