Compressed N₂O Gas for purchase — cylinder-filled nitrous oxide ready for ordering
Customers who want compressed N₂O gas for purchase usually ask first about how the product is stored. Strictly speaking, nitrous oxide is liquefied by compression, so a cylinder contains liquid with a gas cushion above it, and REAL GAZ fills it accordingly.

Orders are processed under ISO 9001 quality procedures, with analysis under ISO 17025 and cylinders marked per EN ISO 7225 hazard labelling.
Pure nitrous oxide at room temperature never behaves like a permanent gas such as nitrogen. As long as liquid remains in the cylinder, the pressure stays near the vapour pressure for that temperature, and it only drops when the cylinder is almost empty. This is why a pressure gauge is a poor indicator of contents and why weighing the cylinder is the reliable way to know how much is left.
🏭 Where N₂O Are Used
- ⚙️ Production lines — plants buying N₂O in bulk packs use it for oxidation and deposition steps;
- 🔬 University and institute labs — researchers order single cylinders for flame spectroscopy and gas-phase studies;
- 🏥 Calibration services — metrology labs prepare reference mixtures starting from clean N₂O;
- 🚀 Specialist workshops — trained operators use N₂O for engine and combustion experiments under strict safety control.
💡 Why Choose REAL GAZ
- ✅ Simple ordering — send grade, cylinder size and quantity; we reply with availability and a delivery plan;
- 🧪 Verified fill — each cylinder is weighed after filling and labelled with net content;
- 🎯 Choice of grade — commercial, 3.0 and 4.5 specifications let you match cost to purity;
- 🔒 Return programme — empty cylinders are collected on the next visit, avoiding storage clutter;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- cleaning and drying of used cylinders before refilling;
- fill-by-weight to prevent overfilling of the liquid phase;
- moisture and impurity analysis of production lots;
- pressure and leak testing at the valve outlet.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📋 Before You Order
- confirm the connection type required by your regulator;
- state whether you need liquid-phase or gas-phase withdrawal;
- tell us the expected monthly consumption so we can reserve stock;
- ask for the safety data sheet and handling notes.
When you place an order, mention whether the cylinder will stand in a heated workshop or outdoors. In cold conditions, withdrawal rate falls because the liquid cools as it evaporates, and a gentle ambient warm-up, never direct flame or hot water, can restore flow. Our staff will suggest the cylinder size that suits your flow rate without icing the regulator.
