High purity Nitrogen Regulator — protect ultra-pure nitrogen from cylinder to instrument
The high purity nitrogen regulator from REAL GAZ is made for nitrogen of 99.999 % and higher purity, where a standard regulator could add moisture or contamination. Electropolished internals and metal diaphragms keep diffusion and outgassing low.
Clean-room assembly and sealed packing keep each unit ready for installation.
Clean-room assembly and sealed packing keep each unit ready for installation.
Delivery systems are compatible with ISO 14175 purity classes and verified against ISO 17025 test practice for industrial and laboratory users.
🏭 Where High-Purity Nitrogen Regulators Are Used
- 💻 Electronics — reflow soldering and wafer-handling lines require dry, oxygen-free nitrogen;
- 🔬 Trace-gas analysis — baselines remain quiet when purge gas is not contaminated;
- 💊 Pharmaceutical R&D — blanketing of sensitive compounds avoids oxidation;
- 🔋 Battery research — dry rooms and glove boxes require very low moisture nitrogen.
💡 Why Choose REAL GAZ
- ✅ Metal diaphragm — negligible permeation compared with elastomers;
- 🧪 Electropolished bore — limits adsorption and particle shedding;
- 🎯 Low dead volume — fast purging and quick gas changes;
- 🔒 Tested for tightness — helium leak testing confirms that no air gets in;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- clean-room assembly;
- helium leak testing;
- moisture and oxygen verification of purge;
- double-bag packing.
Cylinders and equipment comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Specifications & Handling Notes
- 📦 Purity grades — suitable for 5.0, 6.0 and ultra-high purity nitrogen;
- 🧰 Seat type — PCTFE or metal for minimal outgassing;
- 🧼 Installation — purge the regulator at least five times before opening to the system;
- 🗂️ Storage — keep sealed until the moment of fitting.
Elastomer diaphragms allow small amounts of oxygen and water vapour to permeate over time, and this can matter when the target is a few parts per billion. A metal diaphragm eliminates that route, which is why it is specified for the most sensitive work. For less demanding use, a polished stainless regulator with a PTFE-based soft seat gives a good balance between cost and performance.
A leak-tight connection is the weakest point in many high-purity systems. Use new copper or nickel gaskets where the fitting design calls for them, tighten to the manufacturer torque, and verify the join with a helium sniffer or a pressure-decay test. A regulator that is excellent on paper cannot protect purity if a poor connection allows even a tiny amount of air to diffuse in.
