Laboratory Oxygen Gas Cylinder — compact cylinders for controlled bench use
A Laboratory Oxygen Gas Cylinder from REAL GAZ is chosen for safe handling at the bench: small to medium water capacity, a quality valve and gas that has been analysed before filling.
Most laboratories prefer 10 or 20 litre cylinders filled to 150 or 200 bar, which gives weeks of use without bulky storage.
Most laboratories prefer 10 or 20 litre cylinders filled to 150 or 200 bar, which gives weeks of use without bulky storage.
Cylinders conform to EN ISO 11117 valve protection, EN ISO 10297 valve design and ISO 17025 documentation for academic and accredited laboratories.
Cylinder choice depends on consumption. A thermal analyser consuming 50 millilitres per minute needs very little oxygen and a 2 or 5 litre cylinder may last months, while a combustion analyser running all day uses a 20 or 50 litre cylinder in weeks. Small cylinders are easier to move and secure, but larger ones reduce changeovers and lower the cost per cubic metre, so we help you balance bench space against refill frequency.
🏭 Where Laboratory Oxygen Cylinders Is Used
- ⚙️ Gas chromatography — oxygen is used as a reaction or carrier-adjacent gas in some detectors and oxidation reactors;
- 🔬 Thermal analysis — TGA and DSC experiments run in oxygen to study oxidation stability of polymers and metals;
- 🏥 Cell culture incubators — controlled oxygen mixtures are prepared from pure oxygen and other gases for research chambers;
- 🚀 Environmental sensing — sensor calibration benches use oxygen as a reference level against nitrogen.
💡 Why Choose REAL GAZ
- ✅ Bench-friendly sizes — cylinders fit safety cabinets and under-bench restraint brackets;
- 🧪 Documented purity — each cylinder ships with a batch certificate showing purity and impurities;
- 🎯 Regulator pairing — we can supply two-stage regulators with stainless diaphragms and clean fittings;
- 🔒 Exchange service — empty cylinders are swapped for filled ones on a planned schedule;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- cylinder interior drying to low dew point;
- verification of valve outlet and thread condition;
- analysis of purity with calibrated reference gases;
- identification label checked against batch record.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ delivers each Laboratory Oxygen Gas Cylinder to research institutes, universities and quality departments in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Always secure the cylinder with a chain or bracket and keep it away from solvents and grease.
At the bench, fit a two-stage regulator with a delivery range suited to low-flow instruments, use stainless-steel or clean copper tubing and test joints with approved leak-detection liquid instead of oil-based sprays. Label the cylinder with the date it was put into service so stock rotation remains simple.
REAL GAZ — laboratory oxygen, safely contained.
