What Nicotine Strength Can I Achieve With These 50ML Shortfills?
The most common and intended nicotine strength achieved with a 50ml shortfill (in a 60ml bottle) is 3mg/ml (0.3%). This is done by adding one 10ml nicotine shot with an 18mg/ml strength.
Here's the simple calculation:
- You start with 50ml of 0mg e-liquid.
- You add 10ml of 18mg/ml nicotine.
- This gives you a total volume of 60ml.
- The total amount of nicotine added is 180mg (10ml * 18mg/ml).
- This 180mg of nicotine is now distributed across 60ml of liquid (180mg / 60ml = 3mg/ml).
Due to the 10ml space available in the bottle and the UK TPD regulation limiting nicotine shots to a maximum of 20mg/ml strength, achieving significantly higher strengths (like 6mg or 12mg) directly in a standard 50ml shortfill bottle is generally not practical.
Achieving 6mg would typically require adding two nicotine shots, for which there usually isn't enough space. Vapers seeking higher nicotine strengths often use 10ml TPD-compliant bottles or nicotine salts.
Are These 50ml Shortfill E-liquids Compatible With My Vape Kit?
50ml shortfill e-liquids are typically formulated with a higher ratio of Vegetable Glycerin (VG) compared to Propylene Glycol (PG). Common ratios include 70% VG / 30% PG or even 80% VG / 20% PG.
High VG e-liquids are thicker and produce larger vapour clouds. They are best suited for:
- Sub-Ohm Vape Kits: Devices using coils with a resistance below 1.0 ohm (О©).
- Direct-to-Lung (DTL) Vaping: A style where you inhale vapour directly into your lungs, common with more powerful devices.
- Advanced Kits: Box mods and tanks designed for cloud production.
These shortfills are generally not recommended for:
Using thick, high-VG shortfills in incompatible low-power devices can lead to poor wicking (the coil can't absorb the liquid fast enough), resulting in muted flavour and potentially burnt coils ('dry hits'). Always check the recommended e-liquid type for your specific device and coils.
