Specialty Gas R-32 — controlled-purity difluoromethane
Specialty gas R-32 from REAL GAZ is difluoromethane purified beyond ordinary refrigerant requirements and supplied with documented impurity levels. It is chosen where a stable, well-defined fluorocarbon is needed rather than a general-purpose charge.
Purity, water content and trace organics are analysed batch by batch so that your process or experiment starts from known conditions.

REAL GAZ supplies this product with analysis methods aligned to ISO 17025 practice and handling in line with ISO 817 and EN 378, suitable for research and precision industrial use.
A specialty grade is more than a higher percentage on a label. For difluoromethane the critical figures are water, air and related halocarbons, because they influence vapour pressure readings, plasma stability and detector baselines. We therefore state the analytical method behind each value and keep retained samples from every lot, so that a result can be reviewed months later if a question arises in your own quality system.
🏭 Where Specialty R-32 Is Used
- ⚙️ Plasma and etch research — difluoromethane serves as a fluorine-carbon source in semiconductor and thin-film process development;
- 🔬 Thermophysical measurements — laboratories need a defined sample when measuring vapour pressure, density and heat capacity;
- 🏥 Component testing — compressor and heat-exchanger developers run test rigs on R-32 of repeatable quality;
- 🚀 Blend development — R-32 is a base component of several newer low-GWP refrigerant blends studied by manufacturers.
💡 Why Choose REAL GAZ
- ✅ Documented impurity profile — you receive figures rather than a general claim of high quality;
- 🧪 Low moisture — dried product protects sensitive instruments and prevents ice formation at expansion points;
- 🎯 Repeatable lots — consistent supply lets you compare results across weeks and projects;
- 🔒 Specialty hardware — clean cylinders and suitable valves reduce the risk of contamination at the connection;
- 📄 Certificate of Analysis (CoA) — issued for each lot, including purity, water content and main impurities.
📊 Specialty Grade Technical Notes
- Molecular formula CH₂F₂, molar mass about 52.02 g/mol, zero ozone depletion potential;
- Critical temperature is around 78 °C, which matters for supercritical and high-temperature test work;
- Flammability is low but real; the lower flammability limit is close to 14 % by volume in air;
- Use stainless steel or compatible fittings and avoid contact with strong oxidisers;
- Purge lines with dry nitrogen before and after use to keep the supply clean.
🔬 Quality Control & Safety
- multi-stage purification and drying;
- gas chromatography of organic impurities;
- moisture and non-condensable analysis;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
