The Hull cell is a type of test cell used to qualitatively check the condition of a electroplating bath. It allows for optimization for current density range, optimization of additive concentration, recognition of impurity effects and indication of macro-throwing power capability. [ 1 ]
The Hull cell replicates the plating bath on a lab scale. It is filled with a sample of the plating solution and an appropriate anode which is connected to a rectifier. The "work" is replaced with a Hull cell test panel that will be plated to show the "health" of the bath. The Hull cell is a trapezoidal container that holds 267 milliliters of a ...
E.C Electroplating went out of business in 2009, leaving the Superfund site “orphaned” as there was no longer a responsible party to pay for the clean-up. In 2016, the EPA estimated that the cleanup for the E.C Electroplating site and surrounding areas would cost around $37 million. [12] [13]
Such zinc electroplating or zinc alloy electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. According to the International Zinc Association, more than 5 million tons are used yearly for both hot-dip galvanization and electroplating. [ 1 ]

When linked in series, the cells had sufficient power to electroplate a small token and to deliver current to acupuncture type needles for therapeutic purposes, but not enough to deliver an electric shock to MythBusters co-host Adam Savage who was instead pranked by co-hosts who hooked him up to a 10,000 volt cattle fence shock generator.

Commercial reference electrodes consist of a glass or plastic tube electrode body. The electrode consists of a metallic silver wire (Ag (s)) coated with a thin layer of silver chloride (AgCl), either physically by dipping the wire in molten silver chloride, chemically by electroplating the wire in concentrated hydrochloric acid (HCl) [3] or electrochemically by oxidising the silver at an anode ...
LIGA consists of three main processing steps: lithography, electroplating, and molding. There are two main LIGA-fabrication technologies: X-Ray LIGA, which uses X-rays produced by a synchrotron to create high-aspect-ratio structures, and UV LIGA, a more accessible method which uses ultraviolet light to create structures with relatively low aspect ratios.
