Laboratory Oxygen Gas — clean oxygen for analytical work
Laboratory oxygen from REAL GAZ is selected for instruments that notice every trace contaminant. Laboratory Oxygen Gas is offered in grades from 4.5 upwards, filled into cleaned cylinders and shipped with a certificate showing key impurities.
It suits benchtop analysers as well as larger research furnaces.

REAL GAZ supplies this product according to ISO 17025 testing competence, EN ISO 9809 cylinders and ISO 2503 regulator guidance, suitable for industrial and laboratory use.
Most analytical methods call for 99.995% oxygen or better, with limits on water below 5 ppm and total hydrocarbons below 0.5 ppm. We match grade to instrument type and method, so you do not carry the cost of purity you never needed.
🏭 Where Laboratory Oxygen Is Used
- 📊 Elemental analysers — combustion oxygen for CHNS and sulfur determination in soils, fuels and foods;
- 💧 Water quality labs — oxidant for total organic carbon and chemical oxygen demand instruments;
- 🔥 Thermal analysis — oxidative atmosphere for TGA and ashing in materials testing;
- 🧫 Microbiology and biotech — defined gas feeds for incubators and bioreactors.
💡 Why Choose REAL GAZ
- ✅ Verified purity — grade selection from 4.5 to 5.0 supports different method requirements;
- 🧪 Dry and clean — low moisture and hydrocarbons help protect detectors and catalysts;
- 🎯 Method-friendly packaging — cylinder sizes sized for steady daily use or occasional runs;
- 🔒 Reliable continuity — scheduled exchange avoids running out mid-sequence;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- purification and purity confirmation;
- trace moisture determination;
- cleaning of cylinders and valves for oxygen;
- leak testing and pressure checks.
Fit a two-stage stainless steel regulator and use clean metal tubing. Leak-test connections with an approved oxygen-compatible solution and keep the laboratory ventilated, since oxygen enrichment increases fire risk.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ serves Laboratory Oxygen Gas customers in universities, testing laboratories and quality departments across Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Talk to us about grade, regulators and a delivery rhythm that fits your testing schedule.
Cylinders are delivered capped and sealed, and we recommend recording the batch number in your laboratory notebook to support method validation. Where several instruments share a supply, we can propose a manifold with automatic changeover to avoid downtime during long runs.
Laboratory managers appreciate predictability. We keep your preferred grade in stock, label batches clearly and tell you in advance if a lot changes, so that method records stay consistent from one delivery to the next. For busy facilities we can supply reserve cylinders on site, so a replacement is always at hand when a pressure gauge drops during an overnight analytical sequence.
REAL GAZ — oxygen your instruments can trust.
