How Many Millilitres Does a Longfill Make Once Mixed
How many ml
does a longfill
make once mixed?
Short answer: 60ml of finished e-liquid. This is the plain-English UK guide to how the longfill format adds up, why the bottle ships half-empty plus what 60ml of finished juice actually looks like compared with standard bottle sizes.
A standard UK longfill produces 60ml of finished e-liquid once mixed. The bottle itself is a 60ml empty-capacity container that arrives pre-filled with 30ml of flavour concentrate. You add 30ml of base from the Mixer Kit (three 10ml nic shots in one kit) to bring it up to 60ml total. 30ml concentrate plus 30ml Mixer Kit equals 60ml finished. The maths is baked in. No measuring required.
Three numbers
define the volume
Concentrate, shots plus finished total. All three are fixed by the format itself.
Concentrate ships in
The amount of flavour concentrate pre-filled into the 60ml bottle when it arrives with you.
Mixer Kit adds
Three 10ml nic shots from a matched Mixer Kit bring the total to 60ml.
Finished e-liquid
Six times the TPD-capped 10ml bottle size. Roughly a week of vaping at typical consumption.
The bottle is designed so the concentrate plus the Mixer Kit add up to exactly 60ml.
A longfill is essentially a two-part format designed to be assembled at home. When you open a new Nixer longfill bottle, you see a 60ml bottle that is only half full. That is deliberate. The bottle ships with 30ml of flavour concentrate inside plus 30ml of empty headspace. The empty space is there for the nic shots you add to finish the mix.
The Mixer Kit contains three 10ml bottles. Each bottle is bottled at the nicotine strength you picked (for example 6mg freebase or 10mg nic salt). When you add all three 10ml bottles into the 60ml longfill bottle, they fill the empty headspace exactly. No overflow. No shortfall. You finish with 60ml of finished e-liquid at the strength you picked and the VG/PG ratio you picked. The maths is intentional.
Why 60ml specifically? The 60ml bottle size is the most common UK longfill format because it produces six times as much e-liquid as a single 10ml TPD bottle. It also sits below the 100ml shortfill size so it does not attract the same volume-tier concerns some retailers have about larger bottles. For most weekly vapers a 60ml bottle lasts between 7 and 14 days depending on device wattage and vape style.
What if I only add some of the Mixer Kit?
Most people should not. The Mixer Kit is calibrated so that all three 10ml bottles go in together to produce the designed 60ml final volume at the intended nicotine strength plus VG/PG ratio. Adding only two bottles gets you 50ml at a slightly different strength and a slightly different ratio. Adding only one gets you 40ml at yet another profile. The format is designed to be used as a complete kit. Partial fills work mathematically but most people get the strength calculation wrong plus end up with a weak or harsh vape.
If you really want to test a flavour before committing to a full 60ml bottle, try a single 10ml TPD bottle from the same brand in the same flavour profile instead. Many UK longfill brands including Nixer offer their most popular flavours in both longfill plus 10ml formats for this reason.
- Standard longfill. 30ml concentrate in a 60ml bottle.
- Matched Mixer Kit. Three 10ml bottles of base plus nicotine at your chosen strength.
- Combined result. 60ml of finished e-liquid ready to vape.
- Partial fills. Possible but not recommended since they throw off the strength plus ratio.
Three stages from
empty to full
What happens to the liquid level in the bottle as you move from unboxing to ready-to-vape.
30ml concentrate + 30ml kit = 60ml finished
Each stage shows the same 60ml bottle at a different point in the mix. The fill level tells you exactly how much liquid is inside.
The 60ml longfill bottle arrives with 30ml of flavour concentrate inside. The other half is empty headspace for the nic shots.
Three 10ml nic shots from one Mixer Kit at your chosen strength. Pour all three into the longfill bottle.
Shake the bottle for 30 seconds then leave to rest for at least 30 minutes. Ready to vape in any compatible kit.
60ml compared
with standard UK bottles
Where a mixed longfill sits against every other common e-liquid bottle size on the UK market.
Six times a 10ml bottle
Every bar represents the finished e-liquid volume available from each format. The 60ml longfill sits between the small single-bottle formats plus the large shortfill setups.
The 60ml mixed longfill format sits in a sweet spot on the UK market. Bigger than any single TPD bottle. Smaller than a full 100ml shortfill setup. Big enough to offer real per-ml savings. Small enough to finish before the flavour starts to fade.
What 60ml of finished
e-liquid actually means
Three different ways to think about the 60ml total once you have it in your hand.
60ml is exactly the same finished volume as six TPD 10ml bottles. Six times the vape juice in a single compact format.
Roughly 10 days of vaping for a moderate user getting through 5-6ml per day. Light pod users can stretch it to 20-30 days easily.
Fills approximately 30 x 2ml pods or 15 x 4ml sub-ohm tanks. One longfill bottle replaces a month of disposable pod purchases.
Every Nixer longfill
finishes at 60ml
The format is consistent across every Nixer flavour in the range. Pick any longfill plus any matched Mixer Kit and you end up with 60ml of finished e-liquid at your chosen strength plus ratio.
