"Less is more" is a phrase that many live by. It also applies when filling CCELL cartridges. You’ve probably noticed that usually the pre-filled cartridges are not filled up to the top and there's always a small headspace above the oil level. How did the headspace end up there? Does this mean you didn't get everything you paid for?


Where Did My Oil Go?


If you purchased pre-filled CCELL carts, some of the extracted oil has been absorbed into the ceramic heating elements. After filling the carts, we usually advise oil manufacturers to let them sit for a while in order for the ceramic atomizer to be fully saturated so that when they land in your hands you can start vaping right away without the need to wait for it to soak in before you enjoy.


CCELL's ceramic heating elements have extremely high permeability and is are able to absorb up to 150mg of the extracted oil, resulting in a part of it seeming like it may be "missing". Additionally, CCELL's cartridges are pressed into the reservoir using an automated pressing machine which may also slightly lower the oil level from the added pressure.


A Purchase Worth Every Penny


During the design stage, our engineers have already considered all the possibilities and made the reservoir larger for headspace. For example, if you purchase a 1 gram cart, the actual full capacity of the cart itself is around 1.25 grams. This design was implemented to allow for the oil to be able to flow naturally and decrease the risk of leakage during transportation or when there are changes in air pressure.


Our goal is to bring the best vaping experience to you and make sure that every penny you spend on CCELL products counts. For more questions, feel free to reach out to us via social media or email!
