? Hydrogen-Oxygen Separation Electrolysis Machine Double Outlet for Laboratory Use Product Overview The hydrogen-oxygen separation electrolysis machine is suitable for chemistry teaching, demonstrating the generation and separation of hydrogen and oxygen when electrolyzing water. It can be used for college classroom, chemistry interest classes, small science laboratories, small popular science exhibitions, chemical research exhibition rooms and other fields. This product is very small gas production, not suitable for industrial medical use, please do not modify or other purposes. Product Parameters Voltage: 12V Power: 400W Capacity: 0.4GAL(1.5L) Product size: 9.8"*4.1"*13.8"(25CM*10.5CM*35CM) Package size: 17"*16"*6"(43CM*41CM*15CM) Net weight/Gross weight: 9.8lbs(4.45kg)/11.5lbs(5.25kg) Product Features Advantages 1. Independent gas : Hydrogen and oxygen have two pipelines, and the generated hydrogen and oxygen will not mix. 2. Full electrolysis : There are many stainless steel tubes, increase the contact area, more adequate electrolysis. 3. Easy to observe : Transparent acrylic material, gas production process is easy to observe. 4. Safety : 12V low voltage power supply, no heat, safe and reliable. 5. Portable : Light weight, small size, can be moved to the place of operation at any time. ? How to use Add the whole bottle of catalyst to water to dissolve, since it will be exothermic when dissolved, please wait for the liquid to cool down before operation.(Catalyst to be provided by the customer.) Remove the hoses of the left and right electrolytic cells, draw the sodium hydroxide solution with a syringe, and then inject the sodium hydroxide solution into the electrolyzer, the height of the liquid needs to exceed the top of the stainless steel tube, and tap water is added to the middle two empty acrylic tubes to a height of 2/3. The power supply is plugged into the power cord, and the XT60 socket at the other end of the power cord is docked with the XT60 plug of the electrolytic cell, and the power supply can be plugged into the socket to generate electricity. Notes 1. The catalyst will change color when it touches the copper tube, which will affect the secondary sales, so please confirm that this product is what you need before the operation, once the catalyst is added, the refund will be refused. 2. It cannot be disassembled privately, and the damage is not warranted if it is disassembled by yourself. 3. If you do not use it for a long time, you need to pour out all the liquid and wash it with tap water. Note: Catalyst to be provided by the customer.
