Signature 50ml: One Bottle, £5.49, and Why That Is the Whole Point
Most collection pages on this site open by telling you how much choice you are about to get. This one does the opposite. The Signature collection holds exactly one product: Signature 50ml, priced at £5.49, supplied at 0mg nicotine. That is it. No device tiers, no strength ladder, no fourteen flavour variants to work through.
A single-product collection is not a mistake and it is not an oversight. It is a 50ml bottle at 0mg, which in UK terms means one very specific thing: a shortfill. And a shortfill is a format that a lot of people buy without ever having had the format itself explained to them properly. They pick one up because the price per millilitre looks good, get it home, and then discover that the bottle is not full, the strength says zero, and nobody told them what to do next.
So this page is less a brand overview and more a proper working guide to the shortfill format, built around the bottle we actually stock. If you already know your way around a 50ml in 60ml bottle and a nic shot, you can skip straight to the sections on device pairing and coil choice. If the phrase shortfill means nothing to you yet, start at the top and by the end of this page you will know exactly what you are buying, what it costs per millilitre against every other format on the site, and what to do with it once it arrives.
Worth saying up front: £5.49 for 50ml works out at just under 11p per millilitre before you add anything to it. That is roughly half what you pay per millilitre for prefilled 10ml nic salts, and a fraction of what you pay per millilitre buying prefilled devices. The shortfill format exists because of a quirk of UK law, but the reason people stay with it is almost always the maths.
Everything we ship is 100% genuine, dispatched the same working day on orders placed before 4pm, with free UK delivery once your basket clears £20.
What a Shortfill Actually Is, and Why UK Bottles Are Shaped This Way
The shortfill format is a direct consequence of the Tobacco and Related Products Regulations, which UK vapers generally just call TPD. Those rules cap the size of any bottle containing nicotine at 10ml. Not 20ml, not 50ml. Ten.
That cap creates an obvious problem for anyone who vapes a reasonable volume of liquid. If you get through 5ml a day in a refillable device, a 10ml bottle lasts you two days, and you end up buying, opening, carrying and disposing of an enormous number of small plastic bottles. It is wasteful, it is expensive per millilitre because you are paying for packaging and compliance overhead on every unit, and it is a nuisance.
The workaround the industry landed on
The 10ml cap applies to bottles containing nicotine. It says nothing about bottles that contain none. So manufacturers began producing large bottles of nicotine-free e-liquid, deliberately underfilled, leaving headroom at the top. You buy the big bottle, and if you want nicotine in it you add it yourself at home. The bottle is short of full, hence shortfill. It is one of the more elegant pieces of regulatory adaptation in any consumer market.
How the 50ml in 60ml format works
The standard configuration, and the one Signature 50ml uses, is 50ml of liquid in a 60ml bottle. That leaves precisely 10ml of empty space, which is not a coincidence: 10ml is the maximum size of a nicotine-containing bottle, so the headroom is sized to accept exactly one nic shot. Pour the shot in, cap it, shake it, and you have 60ml of finished e-liquid.
Why the bottle says 0mg
Because as sold, it genuinely contains no nicotine at all. That is not a marketing position or a lifestyle claim, it is a legal requirement for a bottle of that size. Every 50ml bottle you see anywhere in the UK is 0mg in the bottle. Our entire shortfill e-liquids range runs to 154 products from £3.95 to £19.99, and every one of them is nicotine-free as supplied, which is exactly why the same 154 products also make up our 0mg e-liquids collection. Those are not two different catalogues. They are the same bottles described two ways, because in the UK large bottle and nicotine-free are the same statement.
What this means practically
You have a genuine choice, made at your kitchen table rather than at checkout. You can vape the bottle exactly as it comes and have a completely nicotine-free liquid. Or you can add nicotine to a strength you decide on. The bottle does not commit you to either until you open it, and that flexibility is the second reason people stay with the format after the price has got them through the door.
Buying It Nicotine-Free: Who Actually Vapes 0mg, and Why
There is a persistent assumption that nobody buys 0mg deliberately, and that every shortfill sold is immediately spiked with a nic shot. That is not what we see. A meaningful share of shortfill buyers use the bottle exactly as supplied, and there are several distinct reasons why.
The end of a taper
Plenty of long-term vapers step their nicotine down gradually over months or years. They go from 20mg to 10mg, then into low-strength freebase, then to 3mg, and eventually the number they land on is zero. What they have not lost is the habit itself: the hand-to-mouth action, the pause it creates, the flavour. Vaping a 0mg liquid lets someone keep the ritual while the nicotine is out of the equation entirely. Whether that is the right approach for any given person is a conversation for them and their GP or local stop smoking service, not for a shop, and we are not going to tell you it is.
The mixers
The largest group by volume are people who buy 0mg specifically because they intend to control the final strength themselves. They want 3mg, and 3mg is a strength you cannot readily buy prefilled in a device. Adding one 18mg nic shot to 50ml gets you almost exactly there, and it gets you there in a bottle that costs half as much per millilitre as buying small bottles.
The flavour-first crowd
Some people simply prefer their vape without the throat sensation nicotine brings. At higher power in a sub-ohm setup, even 3mg can feel sharp on the inhale. Vaped at 0mg, the same liquid is smooth and the flavour comes through more clearly, which is why competition and cloud-focused vaping has always skewed towards very low or zero nicotine.
The household reality
A less discussed reason: buying 0mg and shotting it yourself means you can keep one flavour stock and produce different strengths from it. Two people in a house who like the same profile but sit at different nicotine levels can share a supply rather than duplicating it.
Still strictly 18+
Being nicotine-free changes nothing about who can buy it. Signature 50ml and every other bottle in our nicotine-free e-liquids range is an 18+ product, age-verified at checkout like everything else on the site. Zero nicotine is not the same as unrestricted, and we do not treat it as such.
The Cost Per Millilitre Maths: Where £5.49 for 50ml Really Sits
This is the section that convinces most people, so it is worth doing the arithmetic properly rather than waving at it. All the prices below are real prices from this site.
Signature 50ml as supplied
£5.49 for 50ml is 10.98p per millilitre. Call it 11p. If you vape the bottle at 0mg with nothing added, that is your finished cost.
Signature 50ml with a nic shot added
Add one 10ml nic shot and you have 60ml of finished liquid. Nic shots typically sit around the £1 mark, so your total outlay is roughly £6.49 for 60ml, which lands at about 10.8p per millilitre. Adding nicotine to a shortfill makes it very slightly cheaper per millilitre, not dearer, because you have increased the volume by 20% for a small fixed cost.
Against 10ml nicotine salts
Our nicotine salt e-liquids range holds 582 bottles from £2.49 to £3.95. At £2.49 for 10ml you are paying 24.9p per millilitre. At £3.95 you are at 39.5p. So a shortfill is between roughly half and a quarter of the per-millilitre cost of buying small bottles at list price.
Against the 5 for £10 multibuy
The multibuy narrows the gap considerably. Our 5 for £10 e-liquids deal covers 582 bottles and brings each 10ml down to £2, which is 20p per millilitre. That is still nearly double the shortfill rate, but it is a lot closer, and it comes with nicotine already in the bottle and no mixing required.
Against prefilled devices
This is where the gap becomes dramatic. A prefilled big-puff device carries a sealed 2ml nicotine-containing section under TPD rules, and the whole product is priced as a unit rather than by liquid volume. Compare across our prefilled device range and the effective per-millilitre figure is many times the shortfill rate, because you are paying for a battery, a coil, a screen and a housing every time as well as the juice.
The honest caveat
- Shortfills only make sense if you own a refillable device. If you do not, the per-millilitre saving is theoretical.
- You are buying a larger commitment. Fifty millilitres of a flavour you turn out to dislike is a worse mistake than 10ml of one.
- There is a small amount of work involved: pouring, shaking, waiting.
For anyone getting through more than about 10ml a week in a refillable setup, the maths stops being close. For anyone vaping less than that, or still using prefilled devices, the convenience argument often wins and that is a perfectly reasonable call to make.
Adding Nicotine: Nic Shots, Target Strengths and the Arithmetic
If you decide to add nicotine, the process is simple, but the numbers are worth understanding rather than guessing at, because getting them wrong produces a bottle that is either pointless or unpleasant.
What a nic shot is
A nic shot is a 10ml bottle of unflavoured nicotine base, almost always sold at 18mg or 20mg per millilitre, which are the practical and legal ceilings respectively. It contributes volume and nicotine and nothing else. It is not supposed to change the flavour, and a good one barely does.
The formula
Final strength equals the nicotine milligrams you add divided by the total finished volume. One 10ml shot at 18mg contains 180mg of nicotine in total. Put that into 50ml of shortfill and your finished volume is 60ml, so 180 divided by 60 gives you 3mg per millilitre. Use a 20mg shot instead and you have 200mg into 60ml, which is 3.33mg.
Common targets
- 3mg is the classic sub-ohm strength and is what one 18mg shot into 50ml delivers. It suits higher-power devices where you are inhaling a large volume of vapour per puff.
- 6mg requires two shots into 50ml, giving 70ml at roughly 5.1mg, or you reduce the shortfill volume before adding. Two shots is the usual pragmatic route.
- 0mg requires nothing at all, which is the whole appeal for a lot of buyers.
Why you cannot get high strengths this way
You physically cannot mix a 20mg finished liquid from a 50ml shortfill, because the maximum nicotine you can legally buy in one bottle is 20mg per millilitre and diluting it into more liquid can only ever lower that number. If you want 20mg, you buy it prefilled in a 10ml bottle from our 20mg e-liquids collection or in a device. Shortfills are inherently a low-strength format, and that is the single most important thing to understand before you buy one.
Freebase versus salts in a shortfill
Standard nic shots are freebase nicotine, which is what you want in a shortfill destined for a sub-ohm device. Salt-based shots exist but they behave differently: smoother at the same number, which sounds appealing until you realise smoothness at high power in a big-airflow device makes it very easy to take in far more than you intended. For most shortfill uses, freebase at 3mg is the right answer.
Practical mixing
Pour the shot in slowly, cap the bottle tightly, then shake it properly. Not a polite swirl, a genuine thirty second shake until the liquid looks completely uniform. Some people warm the bottle briefly in a hand or a pocket first, which thins the liquid slightly and helps it combine. Then leave it to settle for a few hours before you fill a tank, because freshly shaken liquid is full of tiny air bubbles that will foam in a coil and cause spitting.
Steeping, Shaking and Shelf Life: Looking After a 50ml Bottle
A 50ml bottle is not a two-day purchase. Depending on how much you vape it might be with you for a fortnight or considerably longer, so it is worth treating it slightly better than you would treat a disposable pod.
What steeping actually does
Steeping is the process of letting a freshly mixed or freshly opened liquid sit so the flavour compounds distribute evenly and any harsh top notes soften. The effect is real but it is often overstated. A commercially produced shortfill has usually already had time to settle before it reaches you, so the main reason to steep is after you have added a nic shot rather than on arrival.
A sensible routine
- Shake hard for around thirty seconds immediately after adding a shot.
- Leave the bottle standing upright somewhere cool and dark for at least a few hours, ideally overnight.
- Give it another shake before the first fill.
- Shake briefly before every subsequent fill. Liquids separate slightly over time and a quick shake keeps things consistent.
Storage
Cool, dark and upright. Heat and ultraviolet light are the two things that degrade e-liquid, which is why bottles are sold in opaque or tinted plastic rather than clear glass. A cupboard is ideal. A sunny windowsill, a car dashboard or the top of a radiator will all noticeably change the liquid over a few weeks, usually darkening it and dulling the flavour. Once nicotine is in the bottle, this matters more, because nicotine oxidises with exposure to air, heat and light, which is what turns older liquid amber or brown.
Does the colour matter?
Darkening on its own is not a fault and does not mean the liquid has spoiled. It is a normal consequence of oxidation over time. What you are looking out for instead is a genuinely off smell, visible separation that does not resolve after shaking, or a flavour that has gone flat and papery. Any of those and it is time for a fresh bottle.
Keep the cap on and keep it away from children
Child-resistant closures on UK e-liquid are a legal requirement and they work, but only if you actually close the bottle. Store liquid out of reach of children and pets, which is the same common sense you would apply to any household chemical. If you decant into a smaller travel bottle, and plenty of people do because carrying a 60ml bottle around is impractical, make sure the travel bottle is also child-resistant and clearly labelled with what is in it and at what strength. An unlabelled bottle of unknown strength in a bag is exactly how people end up vaping something far stronger than they meant to.
Travel and pressure
Cabin pressure changes push liquid out of partially full bottles and tanks. If you are flying, seal bottles in a bag, keep them upright, and empty or fully fill your tank rather than leaving it half full. Our accessories range covers the small practical items that make this less annoying.
Which Devices Suit a 50ml Shortfill at 0mg or 3mg
Format and device have to match. A shortfill mixed to 3mg in the wrong device is an underwhelming vape, and the same liquid in the right device is excellent. Here is how to think about it.
Sub-ohm and direct-to-lung
This is the shortfill format's natural home. Sub-ohm devices run coils below one ohm at higher wattage with wide open airflow, producing a large volume of warm vapour that you inhale straight into the lungs. Because each puff carries a lot of liquid, you get plenty of nicotine even at 3mg, and you get through liquid quickly, which is precisely why buying it in 50ml bottles makes financial sense. Our vape kits range spans 2,001 products from £2.99 to £34.99, and the higher end of that is where sub-ohm hardware lives.
Mouth-to-lung pods and higher strengths
Mouth-to-lung devices use tighter airflow and higher-resistance coils, and you draw into the mouth first the way you would with a cigarette. They use far less liquid per puff, which means 3mg often feels too weak in them. If you are running a small MTL pod, 10ml nic salts at 10mg or 20mg are usually a better match than a shortfill. That is not a criticism of either format, just a different job.
Refillable pods in the middle
Between those two sit refillable pod systems, and this is where a lot of people actually are. Our refillable vape pods collection holds 72 options from £5.99 to £10.99, and our pod kits range covers 455 products from £2.99 to £34.99. Many modern pod kits accept both high and low resistance pods, so the same device can run a 3mg shortfill on a low resistance pod at higher power and a 20mg salt on a high resistance pod at lower power. If you are buying hardware specifically to use shortfills, that dual capability is the thing to look for.
Brands worth looking at
For refillable hardware we stock the established names. Vaporesso carries 252 products from £5.95 to £34.99 and is the broadest range on the site. Geekvape runs 30 products from £7.49 to £13.99 and has a reputation for durable, heavily built kit. Aspire and Oxva both cover the refillable middle ground well, with Oxva spanning £2.89 to £24.99 across 159 products. If you are starting from nothing, our vape starter kits page collects 455 options that come with everything you need in the box.
What not to pair it with
You cannot put a shortfill into a prefilled device. Sealed prefilled products are not designed to be opened and attempting it risks the battery and voids any recourse you have. If your only current device is prefilled, buying a 50ml bottle achieves nothing until you also own something refillable.
Coils, Wattage and Wicking With a High-Volume Liquid
Coils are the consumable people most often neglect, and they have more effect on how a liquid tastes than almost anything else. If you are moving to shortfills, this is where a bit of knowledge pays off immediately.
Resistance and what it tells you
Coil resistance is measured in ohms and printed on the coil itself. Lower resistance means more current, more heat, more vapour and more liquid consumed. Higher resistance means the opposite. As a rough guide, anything below 1.0 ohm is heading towards direct-to-lung use and pairs well with low-strength shortfills. Anything above 1.0 ohm is mouth-to-lung territory and pairs better with higher-strength salts. Our vape coils range holds 19 options from £4.95 to £12.95 covering the common fitments.
Stay inside the printed wattage range
Every coil is marked with a recommended wattage window. Running below it gives you a cool, thin, muted vape. Running above it burns the cotton, and once cotton is scorched there is no recovering it. If a coil tastes acrid, it is done. Start at the low end of the range, take a few puffs, and work upwards until the flavour is where you want it rather than starting high and hoping.
Priming, properly
A new coil goes in dry. Put several drops of liquid directly onto the exposed cotton through the ports on the side of the coil, and a couple more down the centre. Fit it, fill the tank, then leave the whole thing standing for a solid five to ten minutes before you take the first puff. Almost every complaint about a coil dying instantly traces back to skipping this step. Cotton takes time to fully saturate and firing it before it has is the fastest way to ruin a new one.
Why thicker liquids need more patience
Shortfills are generally mixed with a higher proportion of vegetable glycerine than small nic salt bottles, because higher VG produces the denser vapour that sub-ohm devices are built around. Thicker liquid wicks more slowly. That has three consequences: prime for longer, avoid chain-vaping ten puffs in a row without pause, and expect the liquid to behave differently in cold weather. A bottle that has been in a cold car will be noticeably thicker than one at room temperature and will struggle to wick until it warms up.
Realistic coil life
A coil in regular use typically lasts somewhere between one and two weeks, though sweeter liquids shorten that considerably because sugars caramelise on the coil and build up a residue. You will notice life ending as a gradual dulling of flavour rather than a sudden failure. When a fresh coil suddenly tastes dramatically better, that tells you how long you had been putting up with a tired one. Buying coils in advance rather than when you need them is the single easiest quality of life improvement in refillable vaping.
Ten Mistakes People Make With Their First Shortfill
We have answered the same questions enough times to know exactly where this format trips people up. None of these are difficult to avoid once you know about them.
- Buying a 50ml bottle without owning a refillable device. The most common one by a distance. A shortfill is liquid, not a product you can vape on its own.
- Expecting 20mg from a shortfill. Not possible. Dilution can only reduce strength, and the strongest thing you can legally add is 20mg per millilitre. Shortfills are a low-strength format by design.
- Filling the bottle to the brim with nic shots. The 10ml of headroom accepts one shot. Two shots means the bottle overflows unless you decant some out first, which people discover the messy way.
- Not shaking properly. A polite swirl does not combine a nic shot with 50ml of thick liquid. Cap it tight and shake it hard for thirty seconds.
- Vaping it straight after shaking. Freshly agitated liquid is full of microbubbles that foam in a coil and cause spitting and gurgling. Let it stand.
- Skipping the coil prime. Ten minutes of patience versus a ruined coil and a mouthful of burnt cotton. It is not a close call.
- Running the tank down to empty. Once the wicking ports are above the liquid line the cotton starts drying out. Refill at around a quarter remaining rather than waiting for the taste to tell you.
- Committing 50ml to an untested flavour. If you are unsure, try the profile in a 10ml bottle from our e-liquids range first. Being wrong about 10ml is an annoyance. Being wrong about 50ml is a bottle you will resent every time you see it.
- Storing it badly. Sunlight and heat will change a bottle over a few weeks. A cupboard costs nothing.
- Decanting into unlabelled bottles. If you carry liquid around, label it with the flavour and the finished strength. Guessing later is how people end up vaping something far stronger than intended.
None of that is meant to make the format sound difficult. It is a bottle of liquid, you pour it into a tank, it works. But shortfills reward five minutes of understanding in a way that prefilled devices deliberately do not, because prefilled devices are designed to need none.
Where Signature Sits Alongside the Rest of Our E-Liquid Range
One bottle in a catalogue of 736 e-liquids invites an obvious question: why buy this one? The honest answer is that format, price and strength are what you are choosing between, and Signature 50ml occupies a clear position on all three.
The format decision
Our overall e-liquids collection spans 736 products from £2.49 to £19.99, and it splits into two fundamentally different things. On one side, 582 bottles of 10ml nicotine salts, ready to vape, priced from £2.49. On the other, 154 large-format shortfills at 0mg, priced from £3.95 to £19.99. Signature 50ml sits in the second group at £5.49, which places it towards the affordable end of the shortfill shelf rather than the premium end.
Against the premium shortfills
The shortfill range reaches £19.99 at the top. Bottles at that level are usually larger, from more established juice houses, or both. At £5.49 you are paying for a straightforward 50ml with sensible per-millilitre economics, which is exactly what most people actually want from an everyday all-day bottle. Keeping a cheaper bottle for daily use and a dearer one for when you fancy something different is a very common approach and a sensible one.
Against nic salts
If you run a small mouth-to-lung pod and get through 2ml or 3ml a day, the honest recommendation is 10ml salts rather than a shortfill. They come at the strength you need, require no mixing, and the 5 for £10 multibuy narrows the price gap substantially. Format should follow hardware, not the other way round.
Against prefilled devices
Prefilled big-puff devices win on convenience and lose on cost. If you currently buy one every few days and you are looking at your monthly spend with mild alarm, a refillable kit plus shortfills is the single largest saving available to you on this site. The trade is that you have to fill things, change coils and charge a device properly rather than just opening a box.
Where to browse next
If you want to see the full large-format shelf, our shortfill e-liquids page is the place to start, and the identical nicotine-free listing approaches the same 154 bottles from the strength side. If you want hardware to go with it, pod kits and vape kits cover the refillable side, and coils is where the consumables live. Current offers across everything sit on our vape deals page.
UK Rules, Compliance and What We Will Not Tell You
Every product we sell is UK-compliant and notified to the MHRA before it goes on sale. That is not optional and it is not a selling point, it is the baseline. But it is worth setting out what the rules actually say, because they explain almost every odd-looking thing about how UK e-liquid is packaged.
The rules that shape this bottle
- Nicotine-containing e-liquid is capped at 20mg per millilitre.
- Nicotine-containing bottles are capped at 10ml, which is why 50ml bottles are 0mg.
- Prefilled tanks and pods are capped at 2ml of nicotine-containing liquid.
- Child-resistant and tamper-evident packaging is mandatory.
- All products must be notified to the MHRA before they can legally be sold in the UK.
Put those together and the shortfill format stops looking like a gimmick and starts looking like the only sensible way to sell e-liquid in volume in this country.
The disposable ban and why refillables matter more now
The UK ban on single-use disposables reshaped the market. Devices that could not be recharged and could not have their liquid replaced disappeared, and the rechargeable prefilled devices in our big puff vapes range took their place. That shift has quietly made refillable hardware more attractive too, because once you have accepted that you are charging a device anyway, the additional step of filling it yourself is a much smaller leap than it used to be. A 50ml shortfill is the natural liquid supply for that setup.
Strictly 18 or over
Every product on this site is for adults aged 18 or over. That includes 0mg liquid, nicotine-free shortfills and every accessory. Orders are age-verified as part of checkout. We do not sell to anyone under 18 and we do not make exceptions for nicotine-free products.
What we will not claim
We sell e-liquid and hardware. We do not describe vaping as safe, safer, healthy or a treatment for anything, we do not present these products as a medical intervention, and we do not tell you what switching will or will not do for you. If you are an adult who currently smokes and you are thinking about your options, the people to talk to are your GP or your local stop smoking service. Our job is to sell you genuine, compliant products, describe them accurately and get them to you quickly. Anyone selling vapes on the basis of health claims is either badly informed or breaking the rules, and usually both.
Buying Signature 50ml From VapeShopOnline
The practicalities, briefly, so you know what to expect when you order.
Price, dispatch and delivery
- Signature 50ml is £5.49, supplied at 0mg in a 50ml bottle.
- Weekday orders in before 4pm are packed and sent the same afternoon.
- Cross £20 and UK delivery is covered.
- Age verification runs as part of checkout on every order.
At £5.49 a bottle, four bottles clears the free delivery threshold with a little to spare. More usefully, one bottle plus a coil pack, or one bottle plus a refillable pod kit, gets you there in a single order and means you are not paying postage on a small basket. That is the basket shape we would suggest if you are moving to shortfills for the first time: the liquid, the hardware to use it in, and spare coils so you are not caught out in three weeks.
Genuine stock
Everything we sell is 100% genuine and sourced through legitimate UK distribution. In e-liquid specifically this matters more than people assume, because counterfeit and unnotified liquid is the part of the grey market with the least oversight. A bottle that has not been through MHRA notification has had nobody check what is in it or at what concentration. We do not stock it, we do not chase the cheapest possible unit cost, and we would rather sell you a bottle we can stand behind.
A sensible first order
If you are new to the format, we would suggest one bottle rather than several. Fifty millilitres is a real commitment to a single profile, and the point of starting with one is to find out whether shortfills suit your device and your routine before you build a shelf of them. Add a coil pack from our coils range at the same time, because you will need one sooner than you think and paying delivery twice is a waste.
If something is wrong
Leaking bottles and damaged packaging are rare but they happen in transit. Contact us with your order number and a description and we will deal with it. Do not decant a damaged bottle into something else first, because that makes it impossible for anyone to assess what actually went wrong.
Where to go from here
If this page has convinced you the format makes sense, the wider shortfill range is where you will spend most of your browsing time from now on. If it has convinced you the opposite, that a small mouth-to-lung pod and prefilled 10ml salts fit your life better, that is a genuinely useful conclusion too and our nic salts range is where to go. Either answer is fine. The wrong outcome is buying a 50ml bottle you have no way of using.

Frequently asked questions
What is Signature 50ml?
It is a 50ml bottle of e-liquid supplied at 0mg nicotine, priced at £5.49, and it is the only product in the Signature collection at VapeShopOnline. Being a 50ml bottle at zero nicotine makes it a shortfill, which is the standard UK large-format e-liquid: 50ml of liquid in a 60ml bottle with 10ml of headroom left at the top.
Why is Signature 50ml 0mg?
Because UK regulations cap nicotine-containing e-liquid bottles at 10ml. Any bottle larger than that has to be nicotine-free as sold, which is why every 50ml bottle in the country, including this one, is listed at 0mg. If you want nicotine in it you add a nic shot yourself at home, which is the whole reason the format exists.
Can I vape Signature 50ml without adding anything?
Yes. As supplied it is a complete, ready-to-use nicotine-free e-liquid. Plenty of people buy shortfills specifically to vape at 0mg, whether they have tapered their nicotine down over time or simply prefer the flavour without the throat sensation nicotine brings. No mixing is required unless you want nicotine in it.
How much nicotine can I add to a 50ml shortfill?
One 10ml nic shot at 18mg gives you 60ml of finished liquid at 3mg per millilitre. A 20mg shot gives you roughly 3.33mg. Two shots gets you to around 5.1mg in 70ml. You cannot reach 20mg from a shortfill because the strongest nicotine you can legally buy is 20mg per millilitre and diluting it can only lower that.
What does Signature 50ml work out at per millilitre?
£5.49 for 50ml is just under 11p per millilitre. Add a nic shot and you have 60ml for roughly £6.49, which is about 10.8p per millilitre. By comparison, 10ml nic salts at £2.49 work out at 24.9p per millilitre, and even on the 5 for £10 multibuy they are 20p per millilitre.
What kind of device do I need for a shortfill?
A refillable one. Shortfills suit sub-ohm and direct-to-lung devices best, and they work well in refillable pod kits that accept low resistance pods. They are not a good match for tight mouth-to-lung pods, where a 3mg mix usually feels too weak and 10ml nic salts at 10mg or 20mg are the better choice.
Can I put a shortfill into a prefilled device?
No. Prefilled devices are sealed products that are not designed to be opened, and prising one apart risks damaging the battery and leaves you with no recourse if something goes wrong. If a prefilled device is all you own, a 50ml bottle is not usable until you also buy something refillable.
How do I mix a nic shot in properly?
Pour the shot in slowly, cap the bottle tightly, and shake hard for around thirty seconds until the liquid looks completely uniform. A gentle swirl is not enough for a thick liquid. Then let it stand for a few hours before filling a tank, because freshly shaken liquid is full of microbubbles that foam in a coil and cause spitting.
Does a shortfill need steeping?
Not usually on arrival, since commercially produced bottles have generally had time to settle before they reach you. Steeping matters most after you add a nic shot. Shake it, leave it upright somewhere cool and dark overnight, then shake again before the first fill. Give it a quick shake before every refill after that.
How should I store a 50ml bottle?
Cool, dark and upright, with the cap properly closed. Heat and sunlight are what degrade e-liquid, which is why bottles are sold in tinted or opaque plastic. A cupboard is ideal. Keep it out of reach of children and pets, and if you decant into a travel bottle, use a child-resistant one and label it with the flavour and finished strength.
Is it normal for the liquid to go darker over time?
Yes, particularly once nicotine has been added, because nicotine oxidises with exposure to air, light and heat. Darkening on its own is not a fault and does not mean the bottle has spoiled. What would concern you is an off smell, separation that will not shake out, or a flavour that has gone flat and papery.
Is a nicotine-free e-liquid still restricted to over 18s?
Yes. Every product on this site is sold only to adults aged 18 or over, including 0mg liquid, nicotine-free shortfills and accessories. Age verification runs as part of the checkout process on every order without exception. Zero nicotine does not mean unrestricted.
Should I buy a 50ml bottle as my first ever e-liquid?
Probably not. Fifty millilitres is a real commitment to one flavour profile, and if you turn out not to like it you have a large bottle you will not use. If you are unsure, try the profile in a 10ml bottle first. Once you know what you like and you have a refillable device, the shortfill maths is hard to argue with.
Do I get free delivery on a single bottle?
Not on its own. UK delivery is free on orders over £20, and a single £5.49 bottle falls well short. Four bottles clears it, but a more useful basket is one bottle plus the hardware or coils you will need to use it, which gets you over the threshold and means you are not paying postage twice in a month.
