What are Vape liquids ?
E-liquid, Eig Juice or vape juice is the liquid that is used in all electronic cigarettes. It is the liquid contained in vape tanks and indisposable vapes that gets transformed into vapour when heated and then gets inhaled. It is made up of five main ingredients which are Propylene Glycol (pg), Vegetable Glycerine (vg), these are the base carriers, Water, food grade flavourings and in some cases Nicotine (not all el-iquids contain nicotine). All E-liquids sold by us match or exceed the regulation enforced by the UK government and are tested to guarantee they are safe, with backing from the NHS from 2015, stating that e-cigarettes are 95% less harmful than traditional cigarettes.
All vape juice are not the same, some have a variation on the ratio of pgvg which alter the taste or the viscosity of the e-liquid, some have a different mixture of flavours from one flavour to a more complex 14 flavour fusion vaping outlaws mayhem. There are thousands of amazing flavours to choose from, all unique and with their own flavour notes. Browse through our guides for more help and information on vape juice and nicotine or have a look below at some of the most common vape liquid questions.

Starter E-liquids
Starter vape liquids come in 10ml bottle size and in a range of nicotine strengths, they are the best choice for people trying vaping or those who want to replicate the feeling of smoking a cigarette.
Main features of Starter vape liquids:
- Higher pg ratio for stonger throat hit
- Best for those switching from smoking
- 10ml bottle size

Nic Salts
Nic salts are vape liquids that contain salt nicotine instead of freebase nicotine, the salt nicotine offers a smoother throat hit than freebase nicotine, meaning you can have a higher dose of nicotine without a super harsh throat hit.
Main features of Nic salts:
- Less throat hit
- Come in 10ml bottles
- Max strength of 20mg/ml

Shortfills
A short fill is e-liquid with no nicotine in a bottle that has extra space for a nicotine shot/booster. Typically, short fill e-liquids are available in a 60ml bottle which has 50ml of e-liquid and enough space for you to add a 10ml nic shot.
Main features of Short fill e-liquids:
- Ideal for sub ohm vaping devices
- All come without nicotine
- 50ml 100ml or 200ml bottles

Nic Shots
A nic shot is a 10ml bottle of flavourless e-liquid with nicotine that is designed to be diluted into a short fill vape liquid. A nic shot is not to be vaped without diluting it into more e-liquid - typically one nic shot bottle goes into a 50ml shortfill vape juice to give you 3mg of nicotine.
Main features of Nic shots:
- Only to be used with short fill vape liquids
- Come in both freebase or salt nicotine
- Flavourless - 10ml Bottles
What is PV VG?
Vape liquids are made up of a combination of pg and vg - these are PG Propylene Glycol and VG stands for Vegetable Glycerin. they are the main carrier ingredients in e-liquid, each of them have a particular charicteristic, for eg - vg holds flavour better and produces stonger vapour, however it is also very thick and can clog up coils faster, PG produces throat hit and is a lot more viscus. Vape liquids typicaly have a ratio of 50/50 meaning 50% pg and 50% vg. for more detailed info have a look at our pgvg guide

What does TPD E-Liquid Mean?
Eliquid containing nicotine that is sold in the UK is subject to EU regulations, these are known as the Tobacco Products Directive (TPD). These regulations set certain limits on the ingredients inside e-liquids and limit the size of bottles within which they can be sold. Currently a maximum nicotine strength of 20mg/ml in a maximum bottle size of 10ml can be sold once it has passed approval. The TPD also sets out the testing and safety requirements of the eliquid that is sold this also includes the eliquid bottle and the messaging on the bottle and box. Here at UK Ecig Store we ensure the most vigorous of testing has been conducted on all our eliquids and only sell those eliquids which have been passed and approved by the MHRA, the MHRA are the government body which regulate the sale of e-liquids in the UK.
What is a 50/50 E liquid?
50/50 e liquid is 50% VG and 50% PG, vg and pg are the main ingredients in vape liquid and each have certain characteristics, have a look at our guides for more info.
What is Nicotine ?
Nicotine is a naturally occuring colourless oily liquid which is best known for being an active element in tobacco. It is most commonly found in smoking cigarettes. It acts as a stimulant in small doses and is used for smoking cessation to relieve cravings and withdrawal symptoms. There is a common myth that Nicotine is the harmful chemical found in cigarettes, however this is not the case Nicotine is relatively harmless and it is in fact other chemicals that are mainly formed via combustion such as carbon monoxide and tar that are much more harmful to your health (source:https://www.nhsinform.scot/healthy-living/stopping-smoking/reasons-to-stop/tobacco).
What is freebase nicotine?
Freebase means that the nicotine is in its purest form compared to the other nicotine derivatives. In turn, the nicotine is much more potent when heated, therefore giving a stronger throat hit, and takes longer to be released into your system, but will also keep your nicotine cravings in check for a longer period of time. This form is the most common form of nicotine found in vape liquids and is the most that resembles the feeling of smoking a real cigarette and so it is the one favoured by those looking to quit smoking.
What is salt nicotine?
Nicotine Salts are another form of Nicotine, they are also derived from tobacco leaves except compared to freebase nicotine, nicotine salts have Benzoic acid added to them, the result is a smother throat hit and the ability to absorb more nicotine and in turn satisfying your nicotine cravings faster. With freebase nicotine as you increase the level of nicotine the throat hit is harsher, with salt nicotine you can increase the nicotine level without the harsh throat hit therefore this is ideal for those who may find eliquids containing traditional nicotine are too harsh on their throat or those needing a faster nicotine fix. You can find the same variety of flavours as you find with freebase nicotine containing elquids, however there is a difference in the level of nicotine where for salt nicotine the common levels are 10mg and 20mg.
What e-liquid is best for sub ohm?
All e liquids including short fill vape juices such as 50ml and 100ml with a higher VG content are best suited to sub ohm devices and tanks. The higher the VG content the denser a vape cloud would be. A rule of thumb would be that any coil rated below 1.0 Ohm is designed for sub ohm e liquids. Its also best to try a lower nicotine level such as 3mg Nicotine first in a subohm device as the throat hit on subohm liquids is stronger than in a mouth to lung device. Subohm devices also tend to use up more eliquid so its worth looking at shortfils if you are using a sohmohm kit, have a look at our shortfil section for a perfect flavour for your subohm kit.
What e-liquid is best for mouth to lung kit?
Most mouth to lung kit coils are rated above 1.0 Ohm and therefore you would want to opt for a 10ml e liquid with a high PG/VG ratio as this will carry the most flavour and provide an easy to vape MTL experience.
What is e-liquid principally made of, and how do they differ?
Vaping e-liquids are made up of four basic ingredients; water, nicotine, flavourings, and a mix of propylene glycol and vegetable glycerin base (most commonly known as PG and VG). PG and VG ratios will differ from e-liquid to e-liquid, depending on the type of consistency the manufacturer is trying to achieve.
If the VG content is higher than the 50%, it will be best used on sub-ohm devices, whereas if the PG concentration is at 50% or higher, a MTL device is suggested, as they are functioning at lower power, and the harshness of the e-liquid could be too much to bear into a Sub-Ohm device. An e-liquid with High PG concentration will be harsher than one with higher VG percentages, therefore this is why they have suggested type of devices.
Here is how they differ below: Propylene Glycol (PG): This is a lab-made liquid that the FDA generally views as safe in food, drugs, and cosmetics. It’s also used to make artificial smoke or fog for performances. It can irritate the lungs and eyes and maybe more harmful for people with chronic lung diseases like asthma and emphysema.
Vegetable Glycerine (VG): Vegetable glycerin, also known as glycerol or glycerine, is a clear liquid typically made from soybean, coconut, or palm oils. It is odorless and has a mild, sweet taste with a syrup-like consistency, and is particularly popular in the cosmetic industry along being utilised for several other uses.
What is a Short Fill E-Liquid?
Short fill e-liquids or short fill vape juices are bigger versions of the regular 10ml(ml) bottles, with the exception on having no nicotine. These bottles are designed in such a way that they are filled less than the bottle size, and this is why they are called short fill, this allows for a 10ml nicotine booster to be mixed in, to create the required nicotine strength for each individual. For example, a 60ml short fill bottle only has 50ml inside, allowing for a 10ml nicotine booster to be mixed in and create a strength of 3mg (milligrams) nicotine. 100ml bottles have 20ml of space available for use with two nicotine boosters. Since they hold a larger quantity of liquid, more nicotine boosters are needed for the same result.
How long can I use e-liquid for once the bottle is open?
Once the eliquid is opened, you should use it within 6 months - after this time the taste of the liquid may change although it is still fine to vape it.
How long will a 10ml bottle of e-liquid last me?
A 10ml bottle of e-liquid will last approximately 5-7 days for tanks that have a coil resistance above 1..0 ohm If you use a sub ohm device then expect to use more than this.
Why is my e-liquid changing colour in my tank?
This can be down to the coil needing to be changed. The carbon that can be built upon the coil can sometimes make its way into the liquid and it is advisable to empty out the liquid, change the coil, and then refill your tank with fresh e-liquid.
