    How to Add a Nic Shot to a 100ml Shortfill (With Ratio Table)

    Shortfills are larger bottles of nicotine-free (0mg) e-liquid, usually 50ml or 100ml, sold in a bigger bottle with space left at the top. That space is for a nicotine shot, a 10ml bottle of unflavoured nicotine. Here is how to add one and what strength you end up with.

    Step by step

    1. Check the bottle size. A 100ml shortfill normally comes in a 120ml bottle, which leaves room for two 10ml shots. A 50ml shortfill normally comes in a 60ml bottle, with room for one shot.
    2. Remove the nozzle. Most shortfill nozzles pull off with a firm pull or twist. Some have a small tab to help.
    3. Add the shot. Squeeze the nicotine shot into the shortfill bottle.
    4. Replace the nozzle and cap, then shake for about a minute so the nicotine mixes evenly.
    5. Leave it to settle for a few minutes before filling your tank.

    Ratio table: final strength

    Most nicotine shots are 18mg or 20mg in a 10ml bottle. The table shows the approximate final strength.

    Shortfill Shots added Total liquid With 18mg shots With 20mg shots
    50ml 1 × 10ml 60ml 3mg 3.3mg
    100ml 1 × 10ml 110ml 1.6mg 1.8mg
    100ml 2 × 10ml 120ml 3mg 3.3mg

    The formula

    Final strength = (shot strength × shot ml) ÷ total ml. For example, two 18mg shots in a 100ml shortfill: (18 × 20) ÷ 120 = 3mg.

    Which device should you use?

    Shortfills are usually high in VG, which gives bigger, smoother vapour. They work best in sub-ohm vape kits and tanks, not in small nic salt pod kits. Browse our shortfills and 100ml shortfills, and read our guide to shortfill e-liquids.

    Safety tips

    • Keep nicotine shots and e-liquids out of reach of children and pets.
    • Wipe up any spills and wash your hands if liquid gets on your skin.
    • Label a bottle once you have added nicotine, so you know its strength.

    Frequently asked questions

    Can I add more than two shots to a 100ml shortfill?

    Only if the bottle has space. Most 100ml shortfills come in 120ml bottles, so two shots is the maximum.

    Do I have to add a nic shot?

    No. Shortfills can be vaped at 0mg if you do not want nicotine.

    Can I use nic salt shots?

    Yes, some brands make nic salt shots. They give a smoother feel at the same strength. Use the same table to work out the final strength.

    Shortfill E-Liquids Explained: How to Add a Nicotine Shot (UK Guide)

    Shortfill e-liquids are one of the most popular ways to buy e-liquid in the UK. They come in larger bottles, usually 50ml or 100ml, and contain no nicotine. Instead, the bottle is left part-empty so you can add a nicotine shot yourself. This guide explains how shortfills work and how to mix them.

    Why are shortfills sold without nicotine?

    UK rules limit nicotine e-liquid to bottles of up to 10ml. Shortfills get around this by selling the flavoured liquid at 0mg in a bigger bottle, with room left for one or more 10ml nicotine shots.

    What is a nicotine shot?

    A nicotine shot is a 10ml bottle of unflavoured nicotine liquid, usually 18mg or 20mg. When you add it to a shortfill, it brings the whole bottle up to a lower, vapeable strength.

    How to mix a shortfill

    1. Open the shortfill bottle and remove the nozzle tip (most twist or pull off).
    2. Add your nicotine shot or shots.
    3. Replace the nozzle and shake the bottle well for a minute.
    4. Leave it to settle for a short while, then fill your tank or pod.

    Quick mixing guide

    Shortfill Nicotine shots (18mg) Final strength (approx.)
    50ml in a 60ml bottle 1 x 10ml 3mg
    50ml in a 70ml bottle 2 x 10ml 5mg
    100ml in a 120ml bottle 2 x 10ml 3mg
    100ml in a 120ml bottle 2 x 10ml (20mg) 3.3mg

    Always check the bottle size on the label, as the space left for shots varies by brand.

    Which devices suit shortfills?

    Most shortfills are high in VG, which makes thicker vapour. They work best in vape kits and sub-ohm tanks with lower-resistance coils. For small pod kits, a 10ml nic salt is usually a better choice.

    Shortfills and the Vaping Products Duty

    Since 1 October 2026, all vaping liquids carry a duty of £2.20 per 10ml, including nicotine-free shortfills. That means a 100ml shortfill carries £22.00 of duty before VAT. Read our Vaping Products Duty guide for full details.
