LABORATORY NITROGEN GAS — clean, consistent nitrogen for the analytical bench
Laboratory nitrogen gas from REAL GAZ is selected for instruments where baseline stability and low contamination matter. Depending on the method, laboratories use 4.6, 5.0 or 6.0 grades, and we supply each with a stated oxygen and moisture ceiling.
Cylinders, single-stage and two-stage regulators and stainless steel tubing can be offered together so that purity is not lost between the valve and the instrument.

Grades and testing are aligned with ISO 17025 expectations, ISO 8573-1 purity classes and the instrument manufacturers' own gas guidelines, for clinical and research laboratories.
Many laboratories consume nitrogen continuously, so a nitrogen generator can complement cylinders as a backup arrangement. Cylinders remain the reference choice for validation work and for instruments that cannot tolerate any variation in supply. Gas filters, traps for moisture and oxygen, and a regular leak check of the delivery line all help keep the baseline flat.
Safety in the laboratory also deserves attention. Nitrogen cylinders should be secured upright, away from heat and fume cupboard exhaust, and kept in a ventilated cylinder store when not in use. Fit an oxygen depletion monitor in small rooms where several cylinders are connected, since an unnoticed leak could slowly reduce the oxygen concentration.
Documentation is kept for audit. Each certificate carries the lot number, the grade and the measured impurities, so accredited laboratories can attach it to their method files. If an inspector asks where a result came from, the gas supplier is one link in the chain that you can demonstrate quickly and clearly.
🏭 Where Laboratory Nitrogen Are Used
- ⚙️ Gas chromatography — Carrier and make-up gas for GC-FID and GC-ECD systems, where trace oxygen can degrade columns;
- 🔬 Evaporation and concentration — Gentle nitrogen streams dry down sample extracts in tubes and vials;
- 🏥 Glove boxes and desiccators — An inert atmosphere protects air-sensitive reagents and samples;
- 🚀 Cryostat and sample storage — Dry nitrogen blankets protect materials against humidity during handling.
💡 Why Choose REAL GAZ
- ✅ Low-oxygen grades — trace oxygen limits support sensitive detectors;
- 🧪 Method-ready guidance — we help match grade to method and column;
- 🎯 Regulator and line advice — stainless steel fittings prevent permeation;
- 🔒 Scheduled cylinder exchange — empty bottles are replaced on a rota so benches never run dry;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- oxygen, moisture and hydrocarbon analysis;
- cylinder purging and evacuation;
- valve cleanliness inspection;
- certificate matched to each lot.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
