Regulator for laboratory Nitrogen cylinders — precise, clean control at the bench
A regulator for laboratory nitrogen cylinders from REAL GAZ offers gentle, finely adjustable outlet pressure for instruments and sample preparation. Low outlet ranges and a sensitive diaphragm give smooth control for delicate set-ups.
Most models are double-stage and stainless steel, which keeps the output steady and the gas clean.

Selections are made with ISO 17025 laboratory practice in mind and use EN ISO 2503 pressure reducers with EN ISO 10297 cylinder valves in mind.
🏭 Where Laboratory Nitrogen Regulators Are Used
- 🔬 LC-MS and GC-MS — nitrogen serves as nebuliser, drying and collision gas;
- 🧫 Evaporators — sample concentration under a gentle nitrogen stream protects delicate analytes;
- 🧪 Glove boxes — inert atmospheres for air-sensitive chemistry are topped up with controlled flow;
- 🧬 Sample storage support — small sample banks use nitrogen for purging and pressure transfer.
💡 Why Choose REAL GAZ
- ✅ Fine adjustment — low-range outlets such as 0–2 bar allow small changes;
- 🧪 Clean gas path — stainless steel and clean assembly protect sample integrity;
- 🎯 Choice of grades — pair with 5.0 or 6.0 nitrogen according to your method;
- 🔒 Accessory range — filters, tubing and manifolds are available for complete installations;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- particle-free assembly;
- low-pressure leak tests;
- accuracy checks on low-range gauges;
- protective capping.
Cylinders and equipment comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Specifications & Handling Notes
- 📦 Outlet — 0–2, 0–4 or 0–10 bar for typical benches;
- 🧰 Cylinder size — 10, 20, 40 or 50 litre cylinders;
- 🔧 Fittings — 6 mm or 1/4 inch compression outlets;
- 🗂️ Good practice — secure cylinders with a chain or bracket at all times.
Many laboratories now generate nitrogen on site, yet cylinders remain important as a back-up and for methods that specify a certified grade. A cylinder with a good regulator offers a quiet, vibration-free supply with a known purity and a traceable certificate. Changing over is quick, and the same regulator can serve several cylinders in turn when a changeover manifold is added.
Pressure stability at the bench is easier to achieve when the line is short and the tubing is of suitable material. Stainless or copper tubing keeps moisture out better than long runs of soft plastic, and a point-of-use filter protects instruments from any particles. Label each line with the gas name and the set pressure so that colleagues can identify it quickly during routine work.
