What are Doublers?
A doubler is a double-strength concentrated vaping liquid (much like a cordial) which needs to be diluted before vaping. All you need to do is import your own nicotine, and add it to the doublers you receive from us. (Trust us when we say it's not as tedious as it sounds!)
- Import your own nicotine
- Purchase a doubler
- Mix your nicotine into your doubler
Our doublers come in bottles twice their volume to make adding your own nicotine a no-fuss process. Basically you take your bottle of doubler, and fill it to the top with nicotine, give it a shake, and it's ready to vape.
But how much nicotine do I need?
There are different "levels" or "strengths" of nicotine used in personal vapourisers (also known as e-cigs), I've tried to outline which level is equivalent to each type of smoker.
24mg/ml Nicotine Heavy, Full-Flavour/Strength Cigarettes
18mg/ml Nicotine Regular
12mg/mL Nicotine Light
6mg/mL Nicotine Ultra Light
0mg/mL Nicotine This means that there is no nicotine in your E-Liquid mixture. Some people enjoy vaping 0-nic liquid for the taste and familiar hand-to-mouth motion.
You can always vape more of a low-strength e-liquid, but if you vape too much nicotine you can feel dizzy or nauseous!
If you start hiccuping, feel nauseous or dizzy while vaping, consider moving to a lower-strength nicotine level.
Ok, I get it. Where to now?
Once you have decided on which nicotine level you want to start vaping, the easiest way to get started is to import nicotine in double the strength of what you want to vape.
If you want to start vaping at 24mg/ml, then you will need to import 48mg/ml nic.
Vape 12mg/ml? Get 24mg/ml.
Adding 15ml of 48mg/ml nicotine to a 15ml 0mg/ml doubler will create 30ml of 24mg/ml e-liquid.
As all Vapoureyes doublers come in bottles twice their volume, a 15ml doubler will come in a 30ml bottle, ready for 15ml of nicotine - basically you just fill the bottle to the top.
You can import your nicotine from anywhere, but China, the USA and New Zealand are by far the most common places to source nicotine. You can use our contact form if you would like a list of suppliers to look at.
WARNING: DO NOT BUY "100% Nicotine" or "PURE NICOTINE". This is the equivalent of 1000mg/ml concentration, and is extremely dangerous to handle by anyone not in a hazmat suit.
Ok, so I've imported my own nicotine and added it to to my doubler, what now?
Give it a shake, and wait for it to steep!
Steeping is the process in which nicotine oxidises inside your e-liquid. This is beneficial to the taste of a good e-liquid, and almost all e-liquid, benefits from steeping. Each product page has a recommended "steep time" before the e-liquid is as it's best, but generally fruits and mints take the shortest amount of time to steep, followed by bakery-type flavours and tobacco.
The shelf-life of e-liquids starts the moment nicotine is added, there is a period of steeping, then a period of ideal oxidisation/flavour, then a period of decline. Generally speaking e-liquid is best consumed within 6 months of adding nicotine, but they do not go "off".
You can speed up the steeping process by giving the e-liquid a shake every once in a while, applying gentle heat (for example, a crock-pot filled with water on low) or some people even use ultra-sonic jewelry cleaners!
Woo-hoo! I've been vaping for a couple weeks now, and want to reduce my nicotine level.
This is were some maths comes in, you'll need to add less nicotine, and instead mix in some flavourless PG/VG
