The Yocan Magneto Ceramic Coil is the only replacement piece that’s best suited for the Yocan Magneto Vaporizer. It’s made of pure ceramic and has a dual-layered atomizer that uses a two-part vaporization process. Each coil has a two-layered ceramic heating element that melts the wax on the first layer and then vaporizes the liquefied material on the second layer. This ensures that you will not experience oxidation or any toxic by-products when you vaporize your concentrates and your extracts.
