Subordinate Hull Cell 267mL. The Hull Cell is a miniature plating unit for producing a cathode deposit that records the character of electroplate at all current densities within the operating range. It is among the most useful tools available to the plating chemist for control of plating baths. It is an indispensable adjunct to standard analytical methods, enabling the skilled operator to determine and control the effects of addition agents, impurities, and purification treatments on the plating electrolyte, many of which cannot be determined by other methods. Practically every plating solution can be controlled or evaluated to varying degrees by the use of the Hull Cell.
