Designed to be used with Large E-Liquid solutions, to add nicotine strength to them. 

Simply Pour the contents of this bottle into large 0mg E-Liquid bottles to mix them.

 How to work out the Nicotine Strength of your liquid when you combine it 

Firstly, This is relatively simple sum, but a calculator will help.
To work out how strong your juice will be after mixing, you divide:
Total Nicotine content by Total ML 

So how do you get those numbers? There's a step by step below to help!
 

• First, Get the total ML (millileter) amount of all the liquid used. 
  • So for example if you buy 1x 50ml bottle of flavour, and 1 x 10ml nicotine shot, that's 60ml total.
• ​Next, Get the total MG of nicotine used. 
  • For example, if you had 1x Nicotine shot, and it was 18mg nicotine strength, it's 1 x 18, or 18mg total.
  • If you had 2 x Nicotine shot, and they were 18mg each nicotine strength, it's 2 x 18, or 36mg total.

​Divide the Total MG by Total ML to get the nicotine strength of the solution. Divide in that order. MG / ML, not ML / MG
Read below for some example equations.

 Equation example 1: 

• You have a flavour bottle that's 80ml, and You have 2 x 10ml nicotine shots that are 18mgeach. 
• Total ML = 100ml (because it's 80ml for the flavours, + 20ml for the 2 shots)
• Total MG = 36mg (because it's 2 shots at 18mg each, so 2 x 18)
• Dividethe Total MG against the Total ML, you get the strength
• 36 / 100 = 0.36
• The Nicotine strength would be 0.36% (or 3.6mg)

 Equation example 2:  

• You have a flavour bottle that's 100ml, and You have 3 x 10ml nicotine shots that are 18mg each. 
• Total ML = 130ml (because it's 100ml for the flavours, + 30ml for the 3 shots)
• Total MG = 54mg (because it's 3 shots at 18mg each, so 3 x 18)
• Dividethe Total MG against the Total ML, you get the strength
• 54 / 130 = 0.415
• The Nicotine strength would be 0.415% (or 4.15 mg)
   

 Equation example 3:  

• You have a flavour bottle that's 50ml, and You have 1 x 10mlnicotine shot that's 18mg. 
• Total ML = 60ml (because it's 50ml for the flavours, + 10ml for the 1 shot)
• Total MG = 18 (because it's 1 shots at 18mg each, so 1 x 18)
• Divide the Total MG against the Total ML, you get the strength
• 18 / 60 = 0.3
• The Nicotine strength would be 0.3% (or 3 mg)
