Ultrabio: Longfill Flavours and Base for DIY E-Liquid Mixing

Ultrabio is for vapers who like to mix their own e-liquid. The range centres on OWL Salt longfill flavour concentrates and liquid base, giving you room to fine-tune flavour, nicotine strength and mix ratio to suit your device and the way you vape.

What Makes Longfill Flavours Different

With a longfill, the concentrated flavour comes in a larger bottle. You top it up with base and, if you want, a nicotine shot; only then is your mix ready for the tank.

That means you can set the flavour intensity and nicotine strength yourself instead of being tied to a fixed, ready-to-vape e-liquid. Flavour profiles range from fruit and ice to creamy dessert-style blends, plus drink-inspired and tobacco notes.

Choose Your Base, PG and VG Wisely

The PG/VG ratio influences how thin your mix is, how clearly the flavour comes through and how much vapour it produces. More VG generally gives you a smoother draw and denser clouds; more PG carries flavour and throat hit more directly.

Ultrabio’s 30PG/70VG liquid base is a solid choice for setups designed for a higher VG content. Just make sure your tank can wick thicker e-liquids reliably.

• Product focus: OWL Salt longfill flavour concentrates and liquid base.
• Who it’s for: you, if you want to dose flavour, nicotine and base separately.
• Mixing principle: top up the longfill with base and an optional nicotine shot, shake well and let it steep according to the product instructions.
• Important: concentrated flavourings should never go into the tank undiluted.
