What Is Nixer Longfill Vape Juice and How Does It Work?
What Is Nixer
Longfill?
Complete explanation of Nixer longfill vape juice plus the five-step mixing process. UK 2026 guide for new Nixer customers.
Nixer longfill vape juice is a UK-made concentrated flavour formula sold in a 60ml bottle containing 10ml of high-strength flavour concentrate plus 50ml of empty mixing space. Customers add their own 18mg nicotine shots plus VG base liquid to the empty space to create finished e-liquid at their preferred nicotine strength. Five-step mixing process takes about 5 minutes: check bottle, add nic shots based on target strength (1 shot for 3mg, 2 for 6mg, 3 for 9mg), fill remaining space with VG base leaving 2-3ml air gap, shake vigorously 2-3 minutes, test plus label. Always yields 60ml of finished e-liquid regardless of strength chosen. Most fruit Nixer flavours shake-and-vape ready immediately. Dessert profiles like Salted Caramel Macchiato benefit from 1-2 weeks steeping in dark cupboard. Nixer concentrates use the same flavour quality as premium pre-mixed e-liquids but at significantly lower per-ml cost (GBP 0.17-0.20 versus GBP 0.42 for premium shortfills – 50-60% saving). UK TPD 2016 compliant. Manufactured in UK by Dispergo Vaping. Available across fruit, dessert, menthol plus tobacco profiles.

Standard format
Universal Nixer longfill format. 10ml flavour concentrate at bottom plus 50ml mixing space for nic shots and VG base.
DIY process
Five-step mixing process: check bottle, add nic shots, fill VG, shake 2-3 minutes, test. Total active time around 5 minutes.
Yield consistency
Always 60ml finished e-liquid regardless of chosen nicotine strength. Higher strength means more nic shots, less VG base.
60ml/10ml format. 5-step mixing. Always yields 60ml finished.

The five core concepts
Five concepts cover everything you need to understand about Nixer longfill format. Once these are clear the rest follows naturally.
Longfill
Concentrated flavour in larger bottle with empty space for customer-added components. 10ml flavour plus 50ml mixing space.
Concentrate
High-strength flavour formulation. The 10ml concentrate flavours the full 60ml once diluted with nic shots plus base.
Nic shot
10ml bottle of 18mg nicotine in VG/PG base. UK TPD standard. Number added determines final strength.
VG base
Pharmaceutical-grade vegetable glycerine that fills remaining space. Provides vapour clouds plus smooth throat hit.
Steeping
Letting mixed e-liquid develop over time. Most fruits ready immediately. Desserts benefit from 1-2 weeks.
How the concepts fit together.
- Longfill describes the bottle format – concentrate plus mixing space in same bottle.
- Concentrate is the high-strength flavour formula that gets diluted to make finished e-liquid.
- Nic shot is the standardised UK TPD nicotine bottle that customers add for strength.
- VG base is the diluent that fills remaining space plus provides vapour characteristics.
- Steeping is the optional development time some flavours need for full character.

What is in a Nixer longfill bottle
Bottle capacity
Standard UK longfill bottle size accommodating concentrate plus mixing space. 120ml bottles also available with proportional 20ml concentrate.
Pre-filled flavour concentrate
High-strength flavour formulation at the bottom of the bottle. Sufficient to flavour the full 60ml once diluted with nic shots plus base.
Empty space for components
Empty space above concentrate for customer-added nic shots plus VG base liquid. Combination of nic shots plus VG always totals 50ml.
Final mixed e-liquid
After mixing the bottle contains 60ml of ready-to-vape e-liquid at chosen nicotine strength (0mg, 3mg, 6mg, 9mg or up to 18mg with all 5 nic shots).
Why the 60ml/10ml split.
- UK TPD 2016 caps pre-mixed nicotine bottles at 10ml and 20mg/ml.
- Longfill format separates flavour concentrate (no nicotine) from nicotine shots.
- 10ml concentrate sufficient to flavour 60ml once diluted appropriately.
- 50ml mixing space accommodates up to 5 nic shots (50ml total).
- Maximum legal finished strength: 18mg/ml using all 5 shots plus zero VG.
- Most users mix at 3-6mg using 1-2 shots plus VG to fill remainder.
How Nixer longfills work: the mixing process
Five-step process from opening the bottle to first vape. Total active time around 5 minutes for most users.
Check the bottle
Open the 60ml Nixer bottle plus confirm 10ml concentrate is at the bottom plus 50ml of empty space remains. Note flavour name plus mix-date for labelling later.
Add nic shots
Add 18mg nicotine shots based on target strength: 1 shot for 3mg, 2 for 6mg, 3 for 9mg. Pour slowly to avoid spillage plus air bubbles. Wear disposable gloves.
Fill with VG base
Top up the remaining space with pharmaceutical-grade VG base liquid. Leave 2-3ml air gap at the top for proper shaking. VG provides vapour clouds plus smooth throat hit.
Shake thoroughly
Secure cap tightly plus shake vigorously for 2-3 minutes using up-and-down motions. Continue until liquid is completely uniform with no streaks or visible separation.
Test plus label
Sample a small amount immediately. Most fruit flavours ready straight away. Label bottle with mix date, flavour plus strength. Steep desserts 1-2 weeks for full flavour.
Mixing technique tips.
- Check the bottle: all Nixer longfills follow the same 60ml/10ml format so technique is consistent.
- Nicotine shots: count aloud before adding to avoid mistakes. UK TPD shots are 18mg/10ml standard.
- VG base: use only pharmaceutical-grade VG. Pour slowly as VG is thick. Leave 2-3ml air gap.
- Shaking: set timer for full 2-3 minutes. Up-down motions not side-to-side. Continue until uniform.
- Testing: wait 30 minutes after mixing for initial settling before judging flavour.
Format comparison
How Nixer longfills compare to other major UK vape e-liquid formats. Each serves different priorities.
Concentrate plus mixing
Concentrated 10ml flavour in larger 60ml bottle. Customer adds nic shots plus VG base. Most customisable plus cost-effective format. 5-minute mixing per bottle.
Pre-mixed plus nic shot
Pre-mixed 50ml nicotine-free e-liquid in 60ml bottle. Customer adds 1 nic shot to make 60ml at single strength. Faster to mix but more expensive plus less customisable.
Pre-mixed 10ml bottles
Pre-mixed nicotine salt e-liquid in 10ml bottles at fixed strengths (typically 10mg or 20mg). No mixing required. Best for pod systems plus MTL devices. Highest per-ml cost.
Single-use complete units
Pre-charged single-use vape device with built-in e-liquid plus battery. Banned in UK from June 2025 due to environmental concerns. Refillable lookalikes plus rechargeable disposables remain available.
When to choose each format.
- Longfill (Nixer): budget-conscious, regular vapers willing to spend 5 minutes per bottle for major savings.
- Shortfill: users wanting easier mixing process, accept higher per-ml cost for convenience.
- Nic salts: pod system or MTL device users wanting no-mix convenience plus higher nicotine satisfaction.
- Disposable replacements: users prioritising convenience over economics, accept highest per-ml cost.
