You will see a variety of cartridge heating elements offered, however the current standard for these is a ceramic cell with an internal heating element.  This can be found in our All glass cartridges , all ceramic cartridges ,Vari-Flow cartridges, our Ceramic Cell carts (round and flat tip).  These ceramic carts will work with vape batteries that function from 3.2-4.8 volts while the lowest range of the voltage will not provide a huge draw, the taste will be optimal.


Choosing the right hole size is an important step when choosing an empty vape cartridge.  These holes may be as small as .9mm and as large as 2.0mm so consider what you will be filling it with and choose accordingly.  If you are using a thin oil it will be important to get a smaller hole size to avoid any chance of leakage through the bottom of the cartridge.   Thick distillates and extracts may require a larger hole size to perform optimally.


Most cartridges are offered in either 1ml or .5 ml sizes.  The ml is approximately correlated to the amount in grams so if you have an applicator that is 1 gram, you will need a 1ml cartridge size.  We have recently seen the popularity of 1ml cartridge increase, though many prefer the compact size of the .5ml and don’t require the larger capacity.
