This collection comprises all freebase nicotine e-liquids stocked at Vapourium, manufactured by both local New Zealand brands and certified international producers. Every product is a notified item under the Smokefree Environments and Regulated Products Act 2020.

Freebase nicotine is the standard form of nicotine used in e-liquid manufacturing. Unlike nicotine salts, freebase nicotine is not bonded with an acid compound, resulting in a higher pH level. This chemical characteristic produces a more pronounced throat sensation at equivalent nicotine concentrations, which is why freebase products are typically formulated at lower strengths. Standard nicotine options across this collection include 0mg/mL, 1mg/mL, 3mg/mL, and 6mg/mL.

The base composition of freebase e-liquids generally features a higher ratio of vegetable glycerine to propylene glycol compared to nicotine salt counterparts. Common VG/PG ratios include 70/30 and 80/20, producing denser vapour output suited to direct-to-lung inhalation. These formulations perform optimally with sub-ohm coil configurations, typically at resistances between 0.15 and 0.8 ohms, powered at wattages ranging from 40W to 120W depending on the specific hardware.

Bottle sizes in this collection include 30mL, 60mL, and 120mL formats, all supplied with child-resistant caps compliant with New Zealand packaging standards. Container materials include LDPE squeeze bottles with fine-tip nozzles and PET bottles with twist-cap closures, depending on the brand and volume.

Ingredient standards require USP-grade vegetable glycerine, USP-grade propylene glycol, food-grade flavouring compounds, and pharmaceutical-standard nicotine. These e-liquids are compatible with refillable tank systems, rebuildable dripping atomisers, rebuildable tank atomisers, and high-wattage pod devices with sub-ohm coil options. All products are restricted to persons aged 18 years and over.
