Laboratory Compressed Air Cylinder — purified air in a cylinder sized for the bench
A Laboratory Compressed Air Cylinder from REAL GAZ is built for analysts who need small, clean, clearly labelled air supplies that fit beside the instrument rather than in a plant room.
Cylinders are available in 10, 20 and 50 litre water capacities, filled with purified air whose moisture and hydrocarbon content are measured before release.
Cylinders are available in 10, 20 and 50 litre water capacities, filled with purified air whose moisture and hydrocarbon content are measured before release.
Cylinder design follows EN 1964, markings follow EN 1089-3, and testing is carried out under ISO 17025, matching the needs of analytical and research laboratories.
Most gas chromatographs consume between 300 and 450 millilitres of air per minute at the detector, so a 50 litre cylinder at 200 bar, holding about 10 cubic metres, lasts for many days of continuous operation. Smaller 10 litre cylinders suit occasional users and mobile instruments. Customers who run several instruments can combine cylinders on a manifold with automatic changeover, so that a sequence is never interrupted when one cylinder runs low.
🏭 Where Laboratory Air Cylinders Are Used
- ⚙️ Flame ionisation detectors — purified air sustains the detector flame with a low, stable background signal;
- 🔬 Atomic absorption spectrometry — oxidant air feeds the burner of flame spectrometers measuring metals in water and soil;
- 🏥 Cell culture and incubation — controlled air supports environmental chambers where particulate and oil contamination must be avoided;
- 🚀 University teaching labs — small cylinders suit teaching benches and short research projects with no central gas system.
💡 Why Choose REAL GAZ
- ✅ Bench-friendly sizes — compact cylinders fit trolleys, cabinets and fume-hood supports;
- 🧪 Purified filling — catalytic and adsorbent stages remove hydrocarbons and moisture before the cylinder is charged;
- 🎯 Clear labelling — contents, grade and pressure are marked in line with EN and CLP requirements;
- 🔒 Closed-loop exchange — empty cylinders are collected, inspected and re-purged before refill;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- evacuation and purge of every cylinder before filling;
- analysis of moisture and total hydrocarbons;
- inspection of valve seats and burst-disc devices;
- pressure holding test after filling.
Use a dedicated stainless or brass regulator with a clean outlet, secure cylinders with chains or brackets, and keep records of cylinder changes. Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
