TECHNICAL GAS LIQUID HELIUM — liquefied helium for instrumentation and cooling
Technical gas liquid helium refers to helium supplied for engineering, instrumentation and laboratory purposes rather than medical breathing. REAL GAZ provides it as a liquid at 4.2 K or as high-purity gas in cylinders and bundles, so users can both cool systems and purge or pressurise them with the same element.
Technical grades are typically 99.996 % (4.6) to 99.999 % (5.0).
Technical grades are typically 99.996 % (4.6) to 99.999 % (5.0).
Specifications reference ISO 14687 purity classes, EN ISO 11114 material compatibility and ISO 9809 cylinders for industrial use.
🏭 Where Technical Liquid Helium Are Used
- 🔭 Detector cooling — space and astronomy instruments rely on liquid helium to maintain extremely low sensor noise;
- 🧊 Cryostat operation — research cryostats are filled with liquid helium to reach temperatures below 10 K;
- 🧪 Gas chromatography — helium gas acts as a carrier in analytical instruments requiring inert, thermally conductive flow;
- 🔌 Superconductor testing — cables and coils are characterised in liquid helium baths to measure critical current.
💡 Why Choose REAL GAZ
- ✅ Dual supply — liquid dewars and gas cylinders can be ordered together for a complete set-up;
- 🧪 Purity grades — 4.6, 5.0 and higher grades are available for different sensitivity levels;
- 🎯 Application advice — our engineers assist with transfer technique, pressure settings and boil-off control;
- 🔒 Reduced loss — suggestions for insulation and recovery cut wasteful helium venting;
- 📄 Certificate of Analysis (CoA) — supplied with every liquid or gas order, showing purity and lot.
🔬 Quality Control & Safety
- helium purification and purity analysis;
- trace oxygen and moisture measurement;
- dewar vacuum and cylinder valve checks;
- leak testing and pressure integrity.
Helium cylinders ship under ADR / UN 1046 and liquid helium under UN 1963; ventilate rooms to prevent oxygen displacement.
📦 Practical Notes on Technical Liquid Helium
Technical helium users often need both phases: liquid for cooling and gas for purging, pressurising dewars, leak testing and carrier flow. Specify one purity class across the whole chain, because a single contaminated cylinder can place air or moisture into a cold system and freeze solid at the coldest point. Use clean, helium-compatible regulators and stainless tubing, purge transfer lines three times before connection, and keep a log of cryostat consumption so your orders match real boil-off and refill rates.
