Heliox – He O₂ Mix for sale — helium–oxygen blends supplied in certified cylinders
Heliox is a breathable blend of helium (He) and oxygen (O₂), and REAL GAZ offers Heliox – He O₂ Mix for sale in a range of ratios, from 21% O₂ in helium to oxygen-rich 50/50 and 30/70 compositions.
Because helium is roughly one-seventh as dense as nitrogen, the mixture flows with far less resistance than air, which is why it is chosen for flow research, diving and specialist clinical programmes.

Each blend is prepared to ISO 6142 gravimetric principles and verified against ISO 6143 comparison methods, with analysis traceable under ISO 17025 practice for industrial, laboratory and hyperbaric customers.
🏭 Where Heliox Mixtures Are Used
- 🌊 Commercial diving — low-density breathing gas that reduces work of breathing and nitrogen narcosis at depth, mixed to the dive plan;
- 🏥 Respiratory programmes — hospitals and research units specify Heliox ratios under their own clinical protocols and approvals;
- 🔬 Fluid-flow research — laminar and turbulent flow studies exploit the low density and viscosity profile of helium–oxygen;
- 🧪 Reference blends — analytical teams use known He/O₂ compositions to calibrate oxygen analysers and leak detectors;
- 🚀 Aerospace testing — low-density atmospheres are used in wind-tunnel and sensor trials where air would distort results.
💡 Why Choose REAL GAZ
- ✅ Exact ratios — every He/O₂ ratio is blended by weight, so the label matches the cylinder contents;
- 🧪 Stable composition — helium and oxygen do not react, giving a long shelf life when cylinders are stored upright and dry;
- 🎯 Wide choice — standard and made-to-order ratios are available in several cylinder volumes;
- 🔒 Oxygen-clean handling — cylinders, valves and fittings are degreased for oxygen service before filling;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📦 Cylinders and Supply
Heliox is normally supplied in aluminium or steel cylinders built to ISO 9809 or EN 1964, with valve outlets chosen for oxygen-rich mixtures such as DIN 477 or CGA 296. Typical fill pressures are 200 and 300 bar, and sizes run from 2 L laboratory bottles to 50 L cylinders and bundles. Ask our team to confirm the ratio, volume and outlet before you place an order; mixtures with more than 23.5% oxygen require oxygen-compatible regulators.
🔬 Quality Control & Safety
- multi-stage helium and oxygen purification;
- precision gravimetric blending with calibrated balances;
- analysis of oxygen content to ±0.1% on traceable reference standards;
- moisture and hydrocarbon screening;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN ISO 11114 material compatibility requirements.
