Laboratory SF₆ Gas — high-purity sulfur hexafluoride for research and analysis
Laboratory SF₆ Gas from REAL GAZ is a high-purity grade of sulfur hexafluoride, commonly 99.99 % or better, intended for research, calibration and tracer work rather than bulk insulation.
Its inertness, high density and detectability at parts-per-trillion level through electron capture detectors make it ideal for sensitive experiments.
Its inertness, high density and detectability at parts-per-trillion level through electron capture detectors make it ideal for sensitive experiments.
Quality control uses ISO 17025 practice and ISO 6142 procedures for standards, suitable for research, analytical and university users.
🏭 Where SF₆ Is Used
- 🌍 Atmospheric tracer studies — researchers release small amounts of SF₆ to track air mass movement and gas exchange in lakes and oceans;
- 🏢 Ventilation testing — building engineers measure airflow and air change rates using SF₆ decay;
- 🔬 Plasma etching research — controlled flows serve as a fluorine source in semiconductor and MEMS prototyping;
- ⚡ Dielectric research — high-voltage laboratories study breakdown behaviour in pure SF₆ and its mixtures with nitrogen.
💡 Why Choose REAL GAZ
- ✅ High purity — low levels of air, water and fluorocarbons give clean baselines;
- 🧪 Calibration mixtures — SF₆ in nitrogen or air standards can be prepared at ppb and ppm levels;
- 🎯 Instrument-ready — cylinders may be supplied with suitable valves and regulators for GC-ECD systems;
- 🔒 Responsible volumes — small cylinders limit the quantity released in an experiment;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- multi-stage purification and ultra-dry processing;
- gas chromatography and moisture analysis;
- precision gravimetric blending for standards;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Handling & Storage of SF₆
Use a clean stainless steel regulator with metal diaphragm and a short stainless or PTFE-lined line to prevent contamination of ppb-level work. Take care to avoid cross-contamination in ventilation studies, because even tiny releases remain detectable for hours. Keep cylinders away from sample storage areas, record the quantity released for each experiment, and where possible capture or scrub effluent from the instrument. Store cylinders upright in a cool, ventilated place.
⚙️ Trusted Gas Solutions
REAL GAZ supplies Laboratory SF₆ Gas and certified standards to universities, institutes and testing laboratories in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Researchers planning tracer releases can ask us for guidance on the quantities, cylinder sizes and release equipment appropriate to their study.
Smaller cylinders of one to ten litres are often sufficient for a research programme, and long-term users can arrange scheduled refills to keep their experiments on track.
Every cylinder carries a label showing the lot number, purity and filling date, which makes it simple to cite the gas source in a laboratory notebook, a thesis or a published methods section.
REAL GAZ — purity for sensitive science.
