High precision Nitrogen Regulator for laboratory — stable low-pressure delivery for analytical benches
A high precision Nitrogen Regulator for laboratory use keeps the outlet pressure steady while the cylinder empties, so instruments receive the same flow at the start and at the end of a cylinder.
REAL GAZ supplies two-stage and diaphragm-sealed laboratory regulators matched to nitrogen 5.0 and 6.0 cylinders, with outlet ranges from a few hundred millibar up to 10 bar.
REAL GAZ supplies two-stage and diaphragm-sealed laboratory regulators matched to nitrogen 5.0 and 6.0 cylinders, with outlet ranges from a few hundred millibar up to 10 bar.
Laboratory regulators are built with stainless steel bodies, metal diaphragms and PCTFE or PTFE seats, which limit permeation and outgassing that would otherwise raise background noise in trace analysis. Typical outlet ranges are 0–2 bar, 0–4 bar and 0–10 bar, with 1/8 inch or 1/4 inch compression outlets for tubing. Gauges follow EN 837-1, and the inlet connection is chosen to suit the cylinder valve standard of your country, such as DIN 477, BS 341 or CGA.
Good laboratory practice extends beyond the regulator itself. Use clean, degreased stainless or copper tubing, purge the line before connecting an instrument, and fit a leak check with a suitable liquid or electronic detector after every cylinder change. Where trace moisture matters, add an in-line purifier or filter downstream. Record the delivery pressure in your instrument log so that drift can be spotted early.
REAL GAZ supplies this equipment in line with EN 837-1, ISO 10156 and related standards, suitable for industrial and laboratory use.
🏭 Where High-Precision Nitrogen Regulators Are Used
- ⚙️ Gas chromatography — nitrogen as carrier, make-up and detector gas needs a drift-free supply so retention times stay repeatable;
- 🔬 Mass spectrometry — LC-MS nebuliser and collision gas lines depend on a regulated, dry nitrogen feed;
- 🏥 Sample preparation — solvent evaporation and blow-down stations run reliably at a fixed low pressure;
- 🚀 Glove boxes and desiccators — inert blanketing keeps moisture-sensitive reagents and materials protected.
💡 Why Choose REAL GAZ
- ✅ Stable outlet pressure — two-stage design minimises the pressure rise that single-stage units show as a cylinder empties;
- 🧪 Clean wetted parts — stainless steel and metal-diaphragm construction suit trace-level work;
- 🎯 Matched purity — regulators are paired with nitrogen grades that fit your detector sensitivity;
- 🔒 Safe handling — integral relief valves and correct inlet fittings protect operators and tubing;
- 📄 Test and inspection record — available with every order on request.
🔬 Quality Control & Safety
- cleaning and inspection of all wetted parts;
- leak testing of seats, seals and connections;
- gauge accuracy and set-point verification;
- protective packing and correct fitting selection.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
