What is meant by the term “Shortfill E-Liquids?

If you are new to the world of vaping, you may have heard the word “shortfill” and been curious about what it refers to.
E-liquid is typically sold in bottles, and a shortfill e-liquid refers to an e-liquid container that is not filled all the way to the top with e-liquid.
Instead, the bottle is “short-filled,” which means that there is some empty space at the very top of the container.

If this is the case, then why would anyone want to purchase an e-liquid that is shortfill?
The ability to add one’s own nicotine at will is the primary motivating factor behind this choice.

The majority of e-liquids may be purchased with varying levels of nicotine, ranging from 0 milligrammes (mg) of nicotine (no nicotine) to 20 mg of nicotine.

Shortfills are a solution for this problem.

If you buy an e-liquid that is a shortfill, you will have the ability to add your own nicotine to the liquid, allowing you to create a personalised strength that is based on your own preferences.
After you have added the desired amount of nicotine to the shortfill container and given it a thorough shake, you are ready to use it.

The question now is: how do you determine how much nicotine to add?

It’s easy; you only need to use the formula that’s below:

(Desired nicotine strength (in mg) / Available nicotine strength (in mg)) x final volume of shortfill e-liquid (in ml) = amount of nicotine to add (in ml)

Because shortfill e-liquids do not come with nicotine, you will need to purchase it separately if you want to use it. It is vital to keep this in mind.
Nicotine can be obtained in many different formats, including nic shots and nicotine salts, for example.

Let’s say you want to create a 3mg strength e-liquid using a 50ml shortfill e-liquid with a nicotine strength of 18mg. The calculation would be:

(3 / 18) x 60 = 10ml

Let’s say you want to create a 5.2mg strength e-liquid using a 50ml shortfill e-liquid with a nicotine strength of 18mg. The calculation would be:

(5.2 / 18) x 70 = 20ml

Vapers have access to a more budget-friendly alternative in the form of shortfill e-liquids, in addition to the added benefit of being able to tailor the amount of nicotine in their vapour.
When compared to buying many smaller bottles of e-liquid with the right nicotine strength, buying a bigger volume of e-liquid and adding your own nicotine allows you to save money. This is because you are effectively purchasing a larger volume of e-liquid.

Vapers who desire the convenience of being able to personalise the nicotine intensity of their e-liquid while also saving money may consider purchasing shortfill e-liquids. In general, shortfill e-liquids are an excellent choice.
You just need to make sure that you follow the necessary calculations and utilise the suitable form of nicotine for your shortfill e-liquid, and before you know it, you’ll be able to enjoy your very own customised e-liquid.


Mix juice makes this whole process very straightforward. Either buy one OR two bottles of nic shots. Adding one bottle of nic shot will give you 60ml of 3mg nicotine e liquid and adding two nic shots, will give you 70ml of roughly 6mg e liquid.
