{"product_id":"electrolysis-hoffman-unit-complete-with-stand-and-electrodes","title":"Electrolysis Hoffman Unit Complete with Stand and Electrodes","description":"Electrolysis is the process of separating the elements of a molecule, typically H2O in the classroom setting, by applying a direct current to force a chemical reaction. The Hoffman Electrolysis apparatus is a robust system for performing this process in the classroom or lab. An H-shaped piece of glass with two graduated tubes (up to 60ml at intervals of 0.2ml) on either side is attached to a central funnel. The tops of the H-glass are sealed with ground-glass stopcocks, and the bottoms are capped with platinum electrodes. A pair of platinum electrodes are included in the kit.  Replacement electrodes for this device are also sold (Platinum Electrodes #501-2 and Carbon Electrodes #4-50104).  The glass tube and funnel, clamps, support stand, and connector cords are also included as well as an instruction guide.","brand":"GSC International","offers":[{"title":"Default Title","offer_id":49507517497621,"sku":"GSC57001-SET","price":165.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/57001-SET.jpg?v=1761839757","url":"https:\/\/unitedsupplycorp.com\/products\/electrolysis-hoffman-unit-complete-with-stand-and-electrodes","provider":"United Supply Corp.","version":"1.0","type":"link"}
