Precision Cryogenic Gas Cylinders

Precision Cryogenic Gas Cylinders — tight control of purity, pressure and boil-off

Sensitive applications call for precision cryogenic gas cylinders in which every variable, from cleanliness to relief setting, is controlled. REAL GAZ prepares vessels with extra cleaning, verified vacuum insulation and tested pressure-building circuits for ultra-pure nitrogen, argon, oxygen and helium.
The result is a cylinder that behaves predictably from the first litre to the last.

Preparation follows ISO 21029-1, cleaning for oxygen service per EN 12300, and purity verification consistent with ISO 17025 laboratory practice.

🏭 Where Precision Cryogenic Cylinders Are Used

⚙️ Metrology laboratories — stable cold sources support calibration of sensors and reference instruments;
🔬 Superconducting systems — liquid helium and nitrogen cool magnets and cryostats where temperature drift must be minimal;
🏥 Optical manufacturing — high-purity argon and nitrogen protect coatings and crystal-growth furnaces;
🚀 Medical device testing — controlled cryogenic cycles verify the durability of implants and sealing parts.

💡 Why Choose REAL GAZ

✅ Extra cleaning — vessels for critical service are degreased and inspected internally;
🧪 Low-drift pressure — tested economiser and relief settings keep delivery pressure stable;
🎯 Documented insulation — vacuum performance and static evaporation rate are checked and recorded;
🔒 Dedicated product service — a vessel stays in one gas service to prevent contamination.
📄 Certificate of Analysis (CoA) — supplied with every order.

📦 Handling & Storage of Precision Cryogenic Cylinders

Keep delivery lines short and purged before first use.
Avoid shock and vibration, which can degrade vacuum insulation.
Record boil-off between fills to detect early insulation faults.
State the impurity limits you require, such as oxygen below 1 ppm or moisture below 3 ppm, so that preparation and testing can be matched.
Use stainless-steel or electropolished tubing downstream; a precision vessel cannot deliver precision gas through contaminated lines.
Ask for a trial period to verify boil-off and delivery pressure against your equipment specification.
Keep dedicated vessels for each application so that traceability and cleanliness remain intact between fills.
Share your process flow diagram with us so that we can recommend relief settings, fill levels and connection hardware suited to your equipment.
