Just like conventional e-liquid vapes, alternative vape devices need tanks/atomizers. These products are specially designed to perfectly heat oil based concentrates to provide a smooth vaping experience. Many of these tanks function similar to traditional vape atomizers, though they will use concentrates in place of vape juice. Some of these atomizers, like the MIG Vapor E-Nail are even designed to function with swappable coils that can be used to vape concentrates or dry herb mixtures.
