Buy Carbon Dioxide Gas — cylinders filled to the grade you specify
If you plan to Buy Carbon Dioxide Gas, REAL GAZ offers liquefied CO₂ in steel cylinders filled to the grade your process requires, from technical to high purity.
Each cylinder is filled by weight, so the quantity you purchase is the quantity delivered, and the grade is confirmed by analysis.
Each cylinder is filled by weight, so the quantity you purchase is the quantity delivered, and the grade is confirmed by analysis.
Purchasing is supported by data: filling follows EN ISO 14175 where welding grades are involved, ISO 17025 practice for analytical grades, and EIGA guidance for food and beverage CO₂.
Carbon dioxide is stored as a liquid with a gas cushion above it, which means a full 40-litre cylinder typically holds around 30 kg of product. Because the content is sold by weight, buyers can compare quotations on a per-kilogram basis. Our sales team confirms the grade, the valve outlet and the arrangement for exchanging empties before the first order ships, so there are no surprises on delivery day.
🏭 Where Carbon Dioxide Is Used
- ⚙️ Beverage carbonation — dispensing systems in bars, restaurants and bottling lines draw food-grade CO₂ from standard cylinders;
- 🔬 Welding shielding — pure CO₂ or argon-CO₂ blends protect the weld pool in MAG welding of structural steel;
- 🏥 Greenhouse enrichment — growers raise CO₂ levels to support plant growth in controlled environments;
- 🚀 Water treatment — CO₂ lowers pH in alkaline process water and remineralises drinking water safely.

📦 Ordering Notes
- Tell us the application, expected monthly consumption and whether you need gas-phase or liquid withdrawal, and we will recommend the right cylinder and grade;
- Food and beverage customers should state this at the time of order so that a food-grade lot with the matching analysis is allocated;
- Keep full and empty cylinders separate on site, close valves fully after use and never refill or decant cylinders yourself;
- Frost on a regulator at high flow is normal for CO₂, but a heated regulator can be added for sustained demand.
