Adjustable Heliox Gas Cylinder — custom helium-oxygen ratios in a single cylinder
An adjustable heliox gas cylinder from REAL GAZ lets you specify the helium-to-oxygen ratio that your process actually needs rather than settling for a stock blend. We fill each cylinder to your target composition, from oxygen-lean mixes of 10% to oxygen-rich blends of 40% or more.
The ratio is documented on the label and on the analysis report, which makes repeat orders easy to reproduce.

Adjustable here means adjustable at order stage: you choose the proportion, we weigh the components into the cylinder and verify the result with a calibrated analyser. Cylinders are offered in common water capacities such as 10, 20 and 50 litres, and filling pressures can be set to match your regulator and downstream equipment. Because helium is a small, light molecule, valve and fitting integrity matter, so every cylinder is leak checked individually.
REAL GAZ supplies this product according to ISO 6142 for gravimetric preparation, EN 1964 for cylinder design and ISO 17025 practice for verification, suitable for engineering and research use.
🏭 Where Heliox Cylinders Are Used
- 🔧 Process development — pilot lines that test several oxygen levels in turn, using one supplier and one documentation format;
- 🌡️ Heat transfer experiments — helium-rich atmospheres chosen for their high thermal conductivity in test rigs and small furnaces;
- 🌬️ Flow and ventilation research — low-density gas used in wind-tunnel style studies and airway flow models;
- 🚀 Aerospace and leak detection — helium-bearing blends for sealing trials where a trace tracer is combined with oxygen.
💡 Why Choose REAL GAZ
- ✅ You set the ratio — specify the exact percentage of each component instead of adapting your process to a fixed blend;
- 🧪 Repeatable batches — recorded weighing data lets us recreate the same composition months later;
- 🎯 Choice of sizes — small portable cylinders for field tests and larger ones for continuous consumption;
- 🔒 Clear labelling — composition, pressure and hazard information are printed so operators can identify the gas at a glance;
- 📄 Certificate of Analysis (CoA) — issued for each custom ratio with the verified composition.
🔬 Quality Control & Safety
- selection of an oxygen-compatible cylinder and valve;
- precision weighing of helium and oxygen components;
- analyser check of the final ratio against your target;
- pressure testing and helium-grade leak checks.
Cylinders comply with ADR / UN transport rules and relevant TPED and EN/ISO requirements.
