Industrial and Laboratory SO₂ — one gas, two demanding worlds
Sulfur dioxide from REAL GAZ serves both the production floor and the analytical bench. Industrial and Laboratory SO₂ is offered in grades matched to each role: robust commercial purity for process use, and tightly specified material for instrument work.
Purity, moisture and residual impurity levels are reported so you can match the grade to your method.

REAL GAZ supplies this product according to ISO 6142, ISO 6143 and ISO 17025 practice for traceable analysis, with cylinders built to EN ISO 9809, suitable for industrial and laboratory use.
Commercial sulfur dioxide is normally supplied at 99.9% or better, while laboratory grades carry tighter limits on water, sulfuric acid and non-volatile residue. Packages range from lecture bottles to 40 litre industrial cylinders, so one supplier can serve both your plant and your quality laboratory.
🏭 Where Industrial and Laboratory Sulfur Dioxide Is Used
- ⚙️ Process industry — bleaching, sulfite production and reducing-agent duty in large-volume operations;
- 🔬 Analytical chemistry — reagent gas for titration, spectroscopy method development and reference preparation;
- 🌫️ Emissions monitoring — a source gas for checking flue-gas analysers and stack monitoring systems;
- 🎓 Teaching and research — controlled experiments on acid rain chemistry and atmospheric reactions in university labs.
💡 Why Choose REAL GAZ
- ✅ Grades for each purpose — choose commercial or high-purity material without paying for more than you need;
- 🧪 Documented composition — impurity and moisture data are reported against your specification;
- 🎯 Flexible volumes — small research cylinders and larger industrial packs from a single source;
- 🔒 Safe, traceable supply — cylinder identification and batch records support audits and incident review;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- purity verification on every batch;
- filling by weight with calibrated scales;
- trace water and acid-impurity determination;
- pressure integrity and valve seal checks before dispatch.
Because laboratory use is sensitive to contamination, use clean, dedicated regulators and purge lines with dry nitrogen before and after sulfur dioxide service. Keep industrial and laboratory cylinders segregated and clearly labelled to avoid grade mix-ups.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
⚙️ Trusted Gas Solutions
REAL GAZ delivers Industrial and Laboratory SO₂ to customers in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. Whether you run a bleaching line or an accredited testing laboratory, we supply the right grade, the right paperwork and practical guidance on safe handling.
Mixed sites often struggle with documentation, so we issue separate, clearly marked certificates for each grade. Our technical staff can also visit to review storage, ventilation and detection arrangements, helping you keep industrial volumes and analytical reference gas managed to the same safety standard.
If your needs change, we can switch you between grades without changing supplier, and we keep the history of your orders so that repeat purchases always match the previous specification. This continuity is valued by quality managers who must demonstrate consistent materials.
REAL GAZ — one supplier from plant to laboratory.
