Shortfills (a.k.a. Shake and Vape or S&V) have a higher concentration of flavor than ready-to-vape e-liquids. Before you use them in a tank or electronic cigarette, you need to add some base. In our product descriptions, we always indicate how much base you need to add. In case you want to add a base with nicotine (i.e., a Nicotine Booster or Nic Shot), we can help you understand how you can achieve the desired nicotine concentration.
Please keep in mind that most shortfills can only be mixed at 0mg/ml or 3mg/ml. A few Shake and Vape can also be mixed at 6mg/ml nicotine. If you are used to vaping with higher nicotine, you can check out our selection of e-liquids. Finally, if you are interested in learning more about the PG/VG ratio, you can check out our Shortfill (Shake and Vape) and PG/VG Calculator.
How much nicotine base should you add to a Shortfill?
Most Shake and Vape e-liquids come in 60ml shortfill bottles filled up to 50ml. Suppose you need to add 10ml to a 50ml Shortfill. If you want to obtain an e-liquid with 3mg/ml (or 0.3%), you can use a 10ml Nicotine Shot with 18mg/ml nicotine. Let us see why: 18mg/ml means 18 milligram per milliliter. Thus, there are 180 milligrams of nicotine in your booster. When you add the nicotine booster to the shortfill, you still have 180mg of nicotine, but now you have 60ml of liquid. 180mg divided by 60ml is 3mg/ml. So the final nicotine strength is 3mg/ml. You can find the most common combinations below.
Shortfills with room for 10ml base:
- Shortfill with 20ml + 10ml base 0mg/ml nicotine = 30ml e-liquid with 0mg/ml nicotine.
- 20ml Shake and Vape+ 10ml base 9mg/ml nicotine = 30ml e-liquid with 3mg/ml nicotine.
- S&V (20ml)+ 10ml base 18mg/ml Nicotine Booster = 30ml e-liquid with 6mg/ml nicotine.
- Shortfill with 50ml + 10ml base without nicotine = 60ml e-liquid with 0mg/ml nicotine.
- 50ml Shake and Vape+ 10ml base 9mg/ml nicotine = 60ml e-liquid with 1.5mg/ml nicotine.
- S&V (50ml) + 10ml base 18mg/ml nicotine = 60ml e-liquid with 3mg/ml nicotine.
Shortfills with space for 20ml base:
- Shake and Vape with 40ml + 20ml base 0mg/ml nicotine = 60ml e-liquid with 0mg/ml nicotine.
- Shortfill (40ml) + 20ml base 9mg/ml nicotine = 60ml e-liquid with 3mg/ml nicotine.
- S&V with 40ml + 10ml base 18mg/ml nicotine + 10ml base 0mg/ml nicotine = 60ml e-liquid with 3mg/ml nicotine.
- 40ml Shortfill + 20ml base 18mg/ml nicotine shot = 60ml e-liquid with 6mg/ml nicotine.
