High purity S₂+ O₂ Regulator — clean wetted surfaces for sensitive gas work
The high purity S₂+ O₂ regulator from REAL GAZ uses electropolished stainless steel and metal or specially selected soft seats, so purity is preserved from cylinder to point of use. Low outgassing and low dead volume help gas quality hold up in analytical work.
Units are cleaned for oxygen service and packed in sealed bags to prevent re-contamination.
Units are cleaned for oxygen service and packed in sealed bags to prevent re-contamination.
Cleaning follows EN ISO 15001, while leak integrity is verified under ISO 10524 principles for industrial and laboratory uses.
🏭 Where High-Purity S₂/O₂ Regulators Are Used
- 🔬 Trace analysis — low-ppm measurements depend on regulators that add no moisture or hydrocarbons;
- 💻 Semiconductor research — experimental lines take oxygen-containing gas under tightly controlled purity conditions;
- 🧫 Materials science — oxidation and sulphidation studies need clean, repeatable gas feed;
- 🚀 Aerospace testing — component test rigs use clean-service regulators for oxidiser-containing gas.
💡 Why Choose REAL GAZ
- ✅ Electropolished finish — smooth internal surfaces reduce adsorption and particle trapping;
- 🧪 Low leak rate — metal-to-metal seals and tested fittings keep atmospheric air out;
- 🎯 Purge-friendly — dual-port designs allow efficient purging after cylinder changes;
- 🔒 Documented cleaning — a cleaning record can accompany the regulator for your quality files;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- electropolishing and passivation of wetted parts;
- particle and hydrocarbon control during assembly;
- helium leak testing to low leak rates;
- sealed double-bag packaging.
Cylinders and equipment comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Specifications & Handling Notes
- 📦 Body material — 316L stainless steel;
- 🧰 Seat options — PCTFE, PTFE or metal, selected by gas;
- 🧼 Purging — use at least five pressurise-and-vent cycles with dry inert gas before service;
- 🗂️ Filtering — an inlet sintered filter is fitted to retain particles.
Even a very pure gas can be degraded by a few seconds of exposure to room air when a regulator is connected. Good practice is to keep the cylinder valve outlet capped until the moment of fitting, use new gaskets for each connection, and purge the regulator body several times before opening the gas to the instrument line. These habits protect parts-per-million level purity far more than most users expect.
Documentation is part of the product. For regulated laboratories, we can provide the material grade of the body and diaphragm, the seat type, the cleaning method and the leak test result. Keeping these records alongside the gas certificate builds a complete traceability file, which is useful during audits and when a method has to be validated against a defined gas delivery system.
