ICH Q3D Class 1 permitted daily inhalation exposure limit for lead (Pb), requiring zero leaded brass in the oil path
Sintered zirconium-oxide ceramic center post and mouthpiece in EV-V-02 (EUR 1.37+ at 500 units) with zero wetted metal
Pharmaceutical-grade borosilicate glass reservoir inert against 8% to 18% monoterpene concentrations over 12 months
Target ceramic surface vaporization window achieved by pairing a 1.4 ohm zirconia core with a 2.0 V to 2.4 V battery
1. ICH Q3D / Ph. Eur. 2.4.20 inhalation elemental limits and wetted cartridge material matrix
Inhalation is the most sensitive route of administration under ICH Q3D (Elemental Impurities) and European Pharmacopoeia general chapter 2.4.20. While oral supplements tolerate higher elemental thresholds, pulmonary inhalation PDEs (Permitted Daily Exposures) cap Class 1 heavy metals at microgram levels: Lead (Pb) at 5.0 ug/day, Cadmium (Cd) at 3.4 ug/day, Arsenic (As) at 1.9 ug/day, Mercury (Hg) at 1.2 ug/day, and Class 2A Nickel (Ni) at 6.0 ug/day.
| Cartridge Architecture | Center Post & Mouthpiece | Tank Material | Heavy-Metal Leach Risk (6-12 Months) |
|---|---|---|---|
| Generic Plated-Brass 510 Clone | Nickel-plated C36000 brass (up to 2.5% Pb) | Standard soda-lime glass or PC | High risk: Pb and Ni leach into acidic terpenes within 30-60 days |
| Empty Vapes V-01 (EV-VAP-001) | 316L surgical stainless steel + ceramic tip | Type I 3.3 borosilicate glass | Zero lead (0.00% Pb alloy); passivation layer prevents ion migration |
| Empty Vapes V-02 Full Zirconia (EV-VAP-002) | 100% sintered ZrO2 zirconia ceramic center post & tip | Type I 3.3 borosilicate glass | Zero metal in wetted reservoir path; inert across pH 3.5-8.5 |
2. Zero-metal wetted path: how ZrO2 zirconia ceramic (V-02) and pillar-less (V-03) cartridges prevent leaching
In a traditional 510 cartridge, the central metal chimney sits submerged inside the extract reservoir from the day of filling until the customer finishes the cartridge. Replacing that central metal tube with sintered zirconium-oxide (ZrO2) ceramic in the Empty Vapes V-02 (0.5 / 1.0 ml, EUR 1.37+ at 500 units) or removing the center pillar altogether in the Empty Vapes V-03 Pillar-Less (0.5 / 1.0 ml, EUR 0.85+ at 500 units) removes 100% of metal surface area from the bulk oil reservoir.
3. Reproducible aerosol dosing: why 1.4 ohm ceramic cores at 1.8 V to 2.4 V prevent thermal degradation
For cannabinoid extract formulations, aerosol reproducibility depends on keeping ceramic coil surface temperature between 175 C and 205 C so cannabinoids and monoterpenes vaporize cleanly without pyrolytic carbonyl formation (which begins above 240 C). Pairing a 1.4 ohm porous ceramic or zirconia cartridge with a constant-voltage variable 510 battery set to 2.0 V to 2.4 V (2.85 W to 4.11 W) delivers consistent 3.5 mg to 5.0 mg aerosol mass per 3-second inhalation.
FAQ
- Does Empty Vapes supply CE, RoHS 2011/65/EU and material declarations for V-01, V-02 and V-03 510 cartridges?
- Yes. Empty Vapes provides hardware specification sheets, RoHS 2011/65/EU heavy-metal compliance documentation, REACH declarations and UN38.3 battery test summaries on request for B2B buyers.
- Are Empty Vapes 510 cartridges registered as Class IIa medical devices under EU MDR 2017/745?
- Empty Vapes supplies unbranded and OEM empty hardware components (316L stainless steel, ZrO2 zirconia ceramic and Type I 3.3 borosilicate glass) under general electrical and chemical compliance (CE, RoHS, REACH). Where a pharmaceutical marketing authorisation holder places an integral drug-device combination product on the market under EU MDR 2017/745 Article 117, the marketing authorisation holder conducts the combination-product conformity assessment on the filled unit.
