Laboratory Gas Cylinders — Clean, Compact Supply for the Modern Laboratory
Laboratory gas cylinders from REAL GAZ deliver the carrier, fuel, zero and span gases that analytical instruments rely on every day. Sizes are chosen for bench-side convenience as well as for long unattended runs.
Purity grades from 4.5 to 6.0 are available, each with a stated impurity profile.
Purity grades from 4.5 to 6.0 are available, each with a stated impurity profile.
Gases are analysed against ISO 8573 quality classes where applicable and prepared under ISO 17025 practice, for chromatography and spectroscopy laboratories.
🏭 Where Laboratory Cylinders Are Used
- ⚙️ Gas chromatography — helium, hydrogen or nitrogen carrier gases move samples through the column with stable flow;
- 🔬 ICP-OES and ICP-MS — high-purity argon sustains the plasma and keeps background signals low;
- 🏥 Atomic absorption — acetylene and nitrous oxide cylinders feed flame systems for metal analysis;
- 🚀 Cell culture and incubators — carbon dioxide and nitrogen mixtures maintain controlled growth atmospheres.
💡 Why Choose REAL GAZ
- ✅ Grade clarity — each cylinder is labelled with purity grade and main impurity limits;
- 🧪 Right-sized packs — 10 and 20 litre cylinders fit under benches, while larger ones feed manifold systems;
- 🎯 Dedicated hardware — regulators, tubing and traps are available to build a clean gas line;
- 🔒 Planned replenishment — regular deliveries prevent interrupted sequences and wasted samples;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- impurity analysis by ppm and ppb methods;
- moisture and hydrocarbon verification;
- cylinder cleaning and conditioning;
- valve outlet and leak testing.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
🔬 Laboratory Safety Tips
Chain every cylinder to a wall or bench, and keep hydrogen and acetylene well away from oxidisers and ignition sources. Install leak detection where flammable gases are used, and use gas-specific regulators and flashback arrestors. For carrier gases, add moisture and hydrocarbon traps near the instrument and replace them on schedule. When a cylinder falls below the recommended residual pressure, change it before baselines begin to drift. A common set-up for a gas chromatography lab is one helium or hydrogen cylinder for carrier gas, one synthetic air cylinder and one hydrogen cylinder for the flame detector, and a certified calibration mixture. Hydrogen generators can reduce cylinder handling, yet cylinders remain valuable as back-up. REAL GAZ can propose the gas list from your instrument manual and prepare a first-fill package for new equipment.
