Accessing Nicotine

It is illegal to trade liquid nicotine in any way in Australia, so you won't find any nicotine products on this Australian site. It is legal to purchase nicotine online from overseas though. So to get around this we created a sister company in New Zealand that you can purchase nicotine products from, you'll find the unflavoured freebase nicotine and salt nicotine for mixing here.

Safety

  • Nicotine is a poison and must be treated with care, especially in high concentrations.
  • Always wear gloves when handling nicotine, 100mg/ml is a high concentration and can absorb through the skin very quickly if spilt, resulting in the equivalent of hundreds or thousands of cigarettes worth of nicotine being absorbed in a very short amount of time.
  • Avoid getting near the eyes and mouth.
  • Always use measuring syringes to ensure the correct amount is added.
  • Always store where children cannot access it, preferably locked away. Nicotine base is a poison and can be lethal if ingested.

What Is A Doubler?

A doubler is a bottle of e-liquid that's half full, at double flavour concentration. The user adds unflavored nicotine, PG (propylene glycol), and VG (vegetable glycerine) to the bottle to achieve their desired nicotine strength and VG/PG ratio. If the volume of the doubler is 60ml the user will add another 60ml combined total of the above elements to bring the finished total volume to 120ml. Doublers are convenient when the user wants a fairly strong nicotine strength without diluting the flavour of an RTV juice too much.

Doubler Calculator

We have a doubler calculator that you can use here:

https://www.wickandwireco.com.au/pages/doubler-calculator

Today we will be explaining how to add nicotine to a doubler flavour bottle, so ensure that you are on the doubler tab at the top of the calculator and not the ready to vape tab.

Let’s explain what we’re looking at in the above image:

  1. Here you need to enter the strength of your nicotine base, if it is purchased from Wick & Wire Co NZ it will be 100 (100mg/ml). Even though 100mg/ml is the most commonly available strength there are other strengths, so always check the labelling on your nicotine bottle and ensure you fill out this field correctly.
  2. Here we need to enter the VG content of the unflavoured nicotine base. A nicotine base is usually 100% PG or 100% VG but does sometimes come in a 50/50 VG/PG (or other) ratio. Use section 2 and 3 to enter these details.
  3. Here we need to enter the PG content of the unflavoured nicotine base. A nicotine base is usually 100% PG or 100% VG but does sometimes come in a 50/50 VG/PG (or other) ratio. Use section 2 and 3 to enter these details.
  4. Here we will enter the liquid volume of the doubler. We're using 60ml as an example here, which means we would have a 120ml bottle with 60ml of liquid in it.
  5. Here we need to enter the VG content of the doubler. A doubler typically has a VG/PG ratio of 50/50 but they can differ so ensure you're entering the correct data here.
  6. Here we need to enter the PG content of the doubler. A doubler typically has a VG/PG ratio of 50/50 but they can differ so ensure you're entering the correct data here.
  7. Here we need to enter our desired finished nicotine strength, we've used 3 (3ml/ml) as an example.
  8. Here we need to enter our desired finished VG concentration, we've used the most common 70 (70%) in this example.
  9. Here we need to enter our desired finished PG concentration, we've used the most common 30 (30%) in this example.
  10. This is the output that’s been calculated from the numbers we have entered above. This is how many millilitres of nicotine base to add to your doubler bottle. In this example, it’s telling us to add 3.6ml of nicotine base to the bottle of flavoured e-liquid. Please note that this amount is not the same for every bottle size and strength, it changes depending on the data we have given to the calculator.
  11. This is the output that’s been calculated from the numbers we have entered above. This is how many millilitres of VG to add to your doubler bottle. In this example, it’s telling us to add 54ml of VG to the bottle of flavoured e-liquid. Please note that this amount is not the same for every bottle size and strength, it changes depending on the data we have given to the calculator.
  12. This is the output that’s been calculated from the numbers we have entered above. This is how many millilitres of PG to add to your doubler bottle. In this example, it’s telling us to add 2.4ml of PG to the bottle of flavoured e-liquid. Please note that this amount is not the same for every bottle size and strength, it changes depending on the data we have given to the calculator.

Please note that whether you're using freebase nicotine or salt nicotine, the mixing ratio is the same.

Process

There are usually two caps on an e-liquid bottle, an outer cap and an inner cap (with a nozzle). We must remove the inner cap to add nicotine to the bottle. This can be difficult as they’re quite tight to ensure a good seal, we do have a tool available that makes it much easier though, you can find it here.

Always use separate measuring syringes for coming into contact with the nicotine base, the VG, and the PG. Using the same syringe for multiple substances will result in cross-contamination.

Carefully draw the correct amount of nicotine into a measuring syringe and add it to the bottle of flavoured e-liquid. Repeat with the VG and PG. Once the three components have been added, replace the bottle caps tightly and shake vigorously for several minutes. This step is crucial as we must ensure that the substances are mixed into the e-liquid thoroughly.

Discard the used syringes, these are single-use items.

Once the nicotine has been mixed, leave it to settle for 24 hours. Before adding any e-liquid to your atomiser, give the bottle a shake.

If you have any further questions please don’t hesitate to contact us, we would rather you be confident than begin this process unsure of yourself.
