Specialty Gas Oxygen — high purity oxygen for sensitive processes
Specialty oxygen from REAL GAZ goes well beyond commercial grade. Specialty Gas Oxygen includes purities up to 5.0 (99.999%) and certified oxygen mixtures in nitrogen or argon for analytical and calibration work.
Total impurity, moisture and hydrocarbon levels are reported so that you can see exactly what you are using.

REAL GAZ supplies this product according to ISO 14687 purity thinking, ISO 6142 blending and ISO 17025 analysis, suitable for industrial and laboratory use.
Grade 4.5 (99.995%) suits most analytical instruments, while 5.0 (99.999%) is chosen where trace moisture and hydrocarbons would harm a process. Certified mixtures of oxygen in nitrogen or argon cover ranges from ppm to 25%, with traceable uncertainty.
🏭 Where Specialty Oxygen Is Used
- 💎 Optical fibre and glass — oxygen is a controlled reactant in preform deposition and quartz processing;
- 💻 Electronics — oxidation and plasma-ashing steps need low moisture and hydrocarbon content;
- 📈 Analytical instruments — oxidising or support gas for TOC analysers, ICP and elemental analysis;
- 🧬 Cell and biotech research — defined oxygen levels in incubators and bioreactor gas mixes.
💡 Why Choose REAL GAZ
- ✅ Purity grades up to 5.0 — choose the level that suits your sensitivity without overspending;
- 🧪 Certified oxygen blends — precise O₂ levels for sensor calibration and controlled atmospheres;
- 🎯 Low-moisture handling — dedicated filling lines limit water and hydrocarbons;
- 🔒 Compatible hardware — stainless steel regulators and cleaned fittings protect the gas on its way to use;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- multi-stage purification and verification;
- precision gravimetric blending for mixtures;
- trace moisture and hydrocarbon analysis;
- pressure integrity and leak checks.
Use oxygen-rated, oil-free regulators with metal diaphragms and purge lines before first use to keep purity. Keep cylinders away from heat and flammables and secure them in a ventilated store.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ supplies Specialty Gas Oxygen to laboratories, high-tech manufacturers and research centres in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Share your purity target and application, and we will recommend a grade and cylinder arrangement.
Specialty gas is only as good as its delivery path, so we recommend dedicated cylinders, clean regulators and short stainless lines. Our team can supply purifiers or point-of-use filters when your process demands lower impurities than the cylinder alone delivers.
Each shipment is accompanied by a certificate listing oxygen content together with the impurities that matter for your use, such as nitrogen, argon, moisture, carbon dioxide and total hydrocarbons, so you can compare it with your own specification. Our advisers also discuss cylinder materials, because aluminium and treated steel cylinders can protect low-level purity better than standard steel, particularly for long storage periods.
