High purity gas regulator — protecting gas purity from cylinder to instrument
A High purity gas regulator must not add contamination to the gas it controls, and REAL GAZ selects units with metal diaphragms and low-permeation seals for this reason.
The result is a delivery line that preserves 5.0, 5.5 and 6.0 grade gases down to the final fitting.

REAL GAZ supplies this regulator according to ISO 14687 gas-quality practice, ISO 10524-2 and EN 837-1, suitable for analytical and electronics use.
Purity can be lost at any joint, so a high purity installation is judged as a system. Use stainless or electropolished tubing, metal-gasket or VCR-type fittings where required, and purge each connection with the process gas before opening to the instrument. Many users add a vent port or purge valve to the regulator so that air trapped after a cylinder change can be flushed away in seconds rather than minutes. Typical ratings are 200 bar inlet and 0-3.5 or 0-10 bar outlet, and leak rates are specified below 1 × 10⁻⁸ mbar·l/s helium for the best units. Store regulators capped, never lay open ports on a bench, and avoid touching internal surfaces. We can quote complete cylinder-to-instrument assemblies for customers who want guidance on layout and materials.
🏭 Where High-Purity Gas Regulators Are Used
- ⚙️ Trace-level analysis — carrier and zero gases must stay free of moisture and hydrocarbons to protect baselines;
- 🔬 Semiconductor tools — process gases enter chambers through fittings that do not shed particles;
- 🏥 Optical fibre production — helium and oxygen streams stay clean for stable glass quality;
- 🚀 Fuel cell testing — hydrogen purity affects performance, so the regulator must not add impurities.
💡 Why Choose REAL GAZ
- ✅ Metal-to-metal sealing — no elastomer is exposed to the gas in the sensing region;
- 🧪 Low dead volume — purge cycles are short and effective with every cylinder change;
- 🎯 Surface treatment — polished or electropolished wetted parts limit trapped moisture;
- 🔒 Documented cleaning — assembly is carried out in clean conditions and bagged for delivery;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- moisture and oxygen ingress checks during testing;
- particle-controlled cleaning and drying;
- helium mass-spectrometer leak testing;
- final purity-sensitive inspection of ports.
Cylinders and fittings comply with ADR / UN transport rules and relevant EN/ISO standards.
