FIELD: study of physicochemical properties of metal solutions. SUBSTANCE: proposed gear is related to devices to study physico-chemical properties of metal solutions and enables bigger number of solutions involving entire concentration interval of compositions from 0 to 100% to be prepared and surface tension and work function of electron of each alloy to be measured desired number of times with one filling of pure components without further depressurization of gear and contact of solution with environment. One gate-dropping bottle with horizontal capillary which ends are inserted inside reservoir located opposite to it are attached to upper halves of far walls of reservoirs and are sealed vacuum-tight. EFFECT: increased functional efficiency of gear. 1 dwg
