These are devices that work with liquid concentrates, for instance, butane hash oil, also known as BHO. These vaporizers sport either a clearomizer, a cartomizer, or a concentrate chamber that can be replaced. A cartomizer is a vape pen attachment that combines the heating coil (atomizer) and the cartridge into a single unit.
They contain a filler material that resembles the filler you might find in a normal atomizer cartridge. On the other hand, a clearomizer is a cartridge that doesn’t contain any filler material at all. They incorporate a metallic tube, which extends up the body’s middle. In some clearomizers, the heating coil is fixed to the tube’s top, whilst in others, it is placed at the bottom.
In either case, a wick of fiber extends from the coil and soaks in the liquid concentrate, carrying it to the coil. To fill up a clearomizer, the top tip has to be taken off and replaced before any inhalation can be done. Occasionally, you may come across certain best vapor pens that, although originally made for herbs, will allow for a replaceable concentrate chamber.
There are also oil vaporizers, which can double as effective wax vapes. Actually, the majority of vaporizer pens are made to be completely compatible with either form of weed concentrate. As mentioned before, certain vape pens are touted to work with herbs, as well as herb concentrate – doing this isn’t recommended though since it is far from ideal to ‘mix the streams’ as it is said.
If you are hell-bent on using just one device for all three forms, then be sure to use separate liquid and dry chambers.
