The Yocan Evolve Vaporizer features an advanced atomizer boasting dual quartz technology, a functional leak-proof coil cap, and a sleek, stealthy design that's ideal for vaping on-the-go. The double quartz atomizer features inert heating rods that slowly heat waxes at low temperatures for smoother, more flavorful vapor. The Yocan Evolve Vape boasts a high powered atomizer that extracts the best flavors and aromas from waxy oils. This dual quartz rod heating chamber does not react chemically to heat, leaving vapor unadulterated. This "true vaporization" enables you to enjoy the essential flavor notes, scents and medicinal benefits of waxy oils without the smoky harshness caused by combustion. Yocan Evolve features 100% medical-grade quartz.
