Electrophoresis is the phenomenon of the movement of electrically charged particles through a liquid or gas as a result of an electric field formed between electrodes immersed in the medium. A mister Arne Wilhelm Kaurin Tiselius whom was born August 10, 1902, in Stockholm developed electrophoresis. Mr.Tiselius also developed chromatography, phase partition and gel filtration. 

Webster’s Dictionary defines Electrophoresis as “the movement of suspended particles through a fluid or gel under the action of an electromotive force applied to electrodes in contact with the suspension.” And it also defines gel electrophoresis (which is a type of Electrophoresis) as “electrophoresis in which molecules (as proteins and nucleic acids) migrate through a gel and especially a polyacrylamide gel and separate into bands according to size.” 
                                                        

For an example of electrophoresis, in an emulsion of rubber latex in an aqueous medium, the rubber droplets tend to acquire an electrical charge by absorption of ions. If a voltage is applied between a pair of electrodes in the emulsion, the rubber particles migrate toward the electrode that has a charge opposite to their own. If this electrode has a particular shape, the rubber particles deposits on it will coalesce to form an article of this shape; this is the process by which surgical rubber gloves and other electroformed articles are manufactured. Also many automotive parts are coated with paint by an electrophoretic deposition process. 
                                             
Several different companies manufacture the machine that performs electrophoresis. I found two that provided me with the most information but I could not find the prices on any of them. The first company that I found is called Hybaid. They had many different types of Electrophoresis machines and I have provided pictures of a few. The machines aren’t very large and they have a tray for the main part of them. Another company I found was Prot@gen. This company provided some information on its products but did not provide and pictures or prices.
