Laboratory Ar-He Mix for purchase — certified argon-helium standards for research and testing
Laboratory Ar-He Mix for purchase from REAL GAZ is aimed at researchers, university departments and testing houses that need small, accurately certified cylinders rather than industrial volumes.
Each lot is analysed, and the composition and uncertainty are reported on the accompanying certificate so that results can be traced in your own quality system.

Laboratory mixtures are produced under ISO 6142-1, assessed per ISO 6143, and reported with the documentation expected by laboratories working to ISO 17025.
Laboratory cylinders are typically 2, 5 or 10 litres, filled to 100 to 150 bar so that a bench regulator can handle them easily. Common helium fractions are 0.5%, 1%, 5%, 10% and 50% in argon. The certificate states the date of preparation, the analytical method and the expanded uncertainty of the helium value, and we recommend using the cylinder within the validity period stated. Where an accreditation body requires a particular reference gas format, tell us and we will check what can be provided.
🏭 Where Laboratory Ar-He Mixtures Are Used
- 🧪 Method validation — accurately known mixtures let analysts verify the response of detectors and sampling lines;
- 🌡️ Thermal conductivity studies — argon-helium ratios provide known conductivity values for calibrating thermal sensors;
- 🎓 University research — teaching and research labs purchase small cylinders for plasma, laser and spectroscopy experiments;
- 🛡️ Safety and leak testing — helium-bearing mixtures help certify enclosures and sealed devices.
💡 Why Choose REAL GAZ
- ✅ Small cylinder formats — bench-friendly sizes avoid buying more gas than a project needs;
- 🧪 Certified composition — the stated percentage comes with an uncertainty value and analysis date;
- 🎯 Flexible orders — one-off cylinders and recurring supply can both be arranged;
- 🔒 Helpful guidance — we advise on regulators, tubing materials and purge steps suited to laboratory work;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- gravimetric preparation with certified weights;
- comparison against reference standards;
- stability checks on stored cylinders;
- leak testing and protective valve caps.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
Secure the cylinder with a bench clamp or chain, fit a regulator with a metal diaphragm and use short lengths of clean metal tubing. Flush the line before measurement, and do not use the cylinder below its minimum certified pressure because composition may shift as the last gas is drawn.
