How to reach a given nicotine strength

Mixing e-liquids with bases

A practical guide for resellers: how to mix 0 mg/ml e-liquids (or bases) with 10 ml nicotine bases to reach the desired final strength, to keep at the counter or explain to your customers.

Wondering what strength a 10 ml nicotine base should have when added to a nicotine-free liquid to obtain a given final strength? No need to calculate: find the starting volume of the nicotine-free liquid in the tables and read the result. We recommend adding no more than 10 ml of nicotine base per liquid, so as not to dilute the flavour too much.

The formula

(strength of the nicotine base × ml of nicotine base) : (ml of nicotine base + ml of nicotine-free liquid) = final strength

Example. A 10 ml base at 18 mg/ml added to 50 ml of 0 mg/ml liquid:

(18 × 10) : (10 + 50) = 180 : 60 = 3 mg/ml
