Mixer Kit = no extras. Standalone = both required. Match supply to usage.

Whether you need extra VG or nic shots for Nixer depends on what you bought. If you bought a Nixer Mixer Kit alongside your Nixer longfill: no extras needed. The kit contains exactly the right nic shots plus VG/PG base for your chosen strength. If you bought just the Nixer longfill: yes you need 18mg/10ml nic shots plus pharmaceutical-grade VG/PG base sourced separately. Quantity depends on target strength: 3mg needs 1 shot plus 40ml VG, 6mg needs 2 shots plus 30ml VG, 9mg needs 3 shots plus 20ml VG. Standalone Nixer longfills require both supplies. Mixer Kit purchases include both. Here is the complete picture covering when extras are needed plus exactly what to buy. For the Mixer Kit details see our how do you mix Nixer longfills with the Nixer Mixer Kit. This article is general consumer information about Nixer supplies.

Three scenarios cover everyone

Match your situation to one of these three to know what you need. Different purchase patterns require different supply approaches.

How to identify your scenario.

• Mixer Kit purchase: if your order includes a “Nixer Mixer Kit” line item with strength variant.
• Standalone longfill: if you bought only the Nixer longfill bottle without a kit pairing.
• Reorder planning: if you have an existing supply situation plus thinking about future purchases.
• Check your past order history for clarity on which pattern you typically follow.

Quantities needed by target strength

The exact nic shot count plus VG/PG base volume needed depends on the strength you want. Each Nixer longfill has 50ml of mixing space to fill regardless of strength.

Reading the table.

• Mixing space is always 50ml total. Whatever combination of shots plus VG you choose must equal 50ml.
• Each shot adds 3mg/ml. Mathematically: 10ml of 18mg shot fully diluted in 60ml gives 3mg/ml.
• Higher strength means less VG. At 18mg max strength, all 50ml is shots so zero VG goes in.
• Most popular: 3mg and 6mg. Account for 80% of UK Nixer mixing.
• Stay within UK TPD limits. Maximum 5 shots gives 18mg/ml which is the practical legal ceiling.

Where to buy supplies

Four supply options for sourcing what you need beyond the Nixer longfill itself.

Cost-effective approach for regular Nixer users.

• 10-pack nic shots from Dispergo: GBP 15-20 (typically GBP 1.50-2.00 each).
• 500ml VG/PG base bottle: GBP 5-8 lasting 12+ mixes.
• Per-mix supply cost works out around GBP 2-3 for 3mg strength.
• Combined with Nixer longfill at GBP 11.99 standard or GBP 10 multi-buy: total per-bottle GBP 12-15 for 60ml mixed e-liquid.
• Per-ml cost: GBP 0.20-0.25 finished e-liquid versus GBP 0.42 premium shortfills.

Mixer Kit vs separate components

Both approaches work. Choose based on usage pattern plus convenience preference.

Mixer Kit makes sense when.

• First-time Nixer customer learning the format.
• Variable strength preferences or experimenting with new variants.
• Single-bottle mixing where convenience outweighs marginal cost.
• No interest in tracking supply inventory or ratio calculation.
• Want pre-measured precision without measurement equipment.

Separate components make sense when.

• Heavy regular vaper consuming 5+ longfills per month.
• Established at single strength preference (typically 3mg or 6mg).
• Want best per-mix economics with bulk supply discounts.
• Have storage space for 500ml VG bottles plus nic shot inventory.
• Comfortable measuring volumes plus calculating ratios.

Cost comparison example for moderate vaper (5 longfills monthly).

• Mixer Kit approach: 5 kits per month at typical pricing.
• Separate approach: 10 nic shots (GBP 17 bulk) plus 500ml VG (GBP 6) lasting roughly 6 weeks.
• Separate approach saves modest amount per month.
• Mixer Kit approach wins on convenience plus simplicity.
• Difference small enough that personal preference can decide.

VG/PG ratio matters

If buying separate VG/PG base, ratio choice affects final e-liquid characteristics. Mixer Kits handle this through variant selection.

70VG/30PG ratio.

• Higher VG produces bigger vapour clouds.
• Suits sub-ohm tanks at 25W or higher.
• Smoother throat hit at higher wattage.
• Best for cloud chasers plus DTL vaping style.
• 3mg or lower nicotine ideal for high volume use.

50VG/50PG ratio.

• Balanced for MTL pod systems.
• Stronger throat hit suits former smokers.
• Faster wicking in pod system coils.
• Best for pen-style devices plus low-wattage pods.
• 6-9mg nicotine matches lower volume MTL vaping.

Other ratios.

• Some specialist suppliers offer 80/20 or 60/40 ratios.
• Less common but valid for specific device or preference reasons.
• For most Nixer customers 70/30 or 50/50 covers all needs.
• Custom ratios typically not worth complexity unless specific reason.

What you should never buy as base

Some products that look like VG but should never be used in e-liquid mixing.

Cosmetic-grade glycerine.

• Sold for skincare or hair products.
• Contains fragrances plus other additives unsafe for inhalation.
• Looks similar but inhalation untested.
• Avoid completely regardless of price.

Food-grade glycerine.

• Sold in baking or food preparation aisles.
• Lacks pharmaceutical purity controls.
• May contain trace contaminants from food processing.
• Pharmaceutical grade only modest cost premium.

Generic unbranded glycerine.

• Source plus grade unverifiable.
• Cost saving small compared to risks.
• Stick with reputable vape suppliers or pharmacy.
• Brand names with USP/BP grade certification only.

Common supply mistakes

Six mistakes that affect Nixer mixing results plus how to avoid them:

Wrong nic shot strength.

• UK TPD standard is 18mg/10ml.
• Some specialist suppliers sell 20mg or higher concentrations.
• Strength calculations in this guide assume 18mg standard.
• Higher concentration shots require recalculation of quantities.

Insufficient VG quantity.

• Running out of VG mid-mix means incomplete bottle.
• Buy 500ml ahead of need rather than 100ml just-in-time.
• 500ml lasts 12 mixes at 3mg, 17 mixes at 6mg.
• Avoid emergency 100ml purchases at higher per-ml cost.

Cheap unbranded base.

• Saves a few pounds upfront.
• Ruins Nixer concentrate quality.
• False economy when paired with quality longfill.
• Pharmaceutical grade pays back in flavour quality.

Mixed-up variant ordering.

• Buying 50/50 ratio for sub-ohm or 70/30 for MTL pod.
• Wrong ratio causes throat hit problems.
• Match VG/PG to device type at supply purchase.
• Verify ratio matches device wattage range.

Stockpiling beyond shelf life.

• Nic shots: 12-18 month shelf life.
• VG/PG base: 24+ months sealed.
• Match buying frequency to consumption rate.
• Avoid bulk buying that exceeds practical use.

Mixing approach mismatch.

• Buying both Mixer Kit plus separate components.
• Doubles supply cost without benefit.
• Choose one approach plus stick with it.
• Switch only if usage pattern changes significantly.

Practical approach

• Mixer Kit = no extras needed. Kit includes everything for chosen strength plus variant.
• Standalone longfill = both required. Need 1-5 nic shots plus 0-50ml VG depending on strength.
• Match supply approach to usage: kits for occasional, bulk components for regular vapers.
• Pharmaceutical-grade VG only. Cosmetic or food grade unsafe for vaping.
• Match VG/PG ratio to device: 70/30 sub-ohm, 50/50 MTL pod.
• Stay within UK TPD limits: 18mg/ml maximum finished strength.
