Hoffman Electrolysis Apparatus with Glass Stopcocks

• Used for demonstrating the electrolytic decomposition of water or determining chemical composition
• Made from heavy duty borosilicate 3.3 glass with glass key stopcock
• Includes Hoffman Electrolysis Apparatus with (2) glass stopcocks, (2) carbon electrodes in rubber stoppers, (2) platinum electrodes in rubber stoppers, and instruction guide
• Required but not supplied: support stand with clamps and 12V DC power supply

The Hoffman Electrolysis Apparatus is used for the demonstration of the chemical composition of water and the production of gases through chemical reactions. The borosilicate glass unit consists of two 50mL capacity outer tubes graduated in 0.2mL increments, connected to a central tube with a 200mL-capacity funnel-shaped bulb. The supplied platinum electrodes mounted in rubber stoppers are used for the electrolysis of acidified water; carbon electrodes are supplied for ammonia solutions, hydrochloric acid, or other chloride-containing solutions. Includes an instruction guide.

NOTE: A support stand with clamps (Eisco part number CH0740F) and 12V DC power supply are required but not included
