Oxygen Helium Breathing Gas for Purchase — heliox blends for deep work and respiratory research, available to order
Oxygen helium breathing gas for purchase is offered by REAL GAZ as heliox in typical ratios such as 80/20, 70/30 and 50/50, as well as deep-bottom blends with 10% to 16% oxygen. Helium is far less dense than nitrogen, which reduces breathing resistance at depth and eliminates nitrogen narcosis.
Because helium is expensive and easily lost, we blend by weight and verify by analysis to avoid wasted gas.
Because helium is expensive and easily lost, we blend by weight and verify by analysis to avoid wasted gas.
Blending follows ISO 6142 for composition accuracy, with breathing quality guided by EN 12021 and cleaning to ISO 15001 for commercial diving and research clients.
🏭 Where Oxygen-Helium Mixtures Are Used
- 🛢️ Deep commercial diving — heliox is the traditional bottom gas for long working dives beyond air limits;
- 🔬 Physiology research — institutes prepare defined mixtures for experiments performed under approved protocols;
- 🏭 Industrial test chambers — heliox is used to simulate low-density gas conditions for equipment trials;
- 🧪 Flow and acoustic studies — helium-oxygen offers high sound velocity and low density for laboratory measurement;
💡 Why Choose REAL GAZ
- ✅ Weighed blending — gravimetric preparation keeps helium use accurate and waste low;
- 🧪 Analysed and certified — helium and oxygen fractions are verified and recorded on the CoA;
- 🎯 Order any ratio — we can prepare custom heliox ratios within safe flammability and oxygen limits;
- 🔒 Careful handling — oxygen-clean preparation and clear marking prevent misuse;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- helium purity check on incoming supply;
- gravimetric blending and rolling;

- valve inspection and leak testing.
Cylinders are made to ISO 9809 and EN 1964, and carried under ADR / UN rules.
🛡️ Safe Handling of Heliox
Heliox lowers gas density, so a leak spreads quickly and high-pitched speech under pressure is normal and not a fault. Oxygen levels in these mixtures can still support combustion, therefore keep cylinders and fittings clean, avoid grease and open flame, and open valves gently. Helium diffuses through damaged seals and some elastomers, so inspect O-rings and hoses frequently and use materials rated for helium service. Store cylinders upright and secured in a ventilated place, and keep a record of every fill and use. We provide safety data sheets with each shipment and are glad to answer technical questions about storage and blending.
