Laboratory Argon-CO₂ Mix for purchase — certified argon-CO₂ mixtures for laboratory buyers
A Laboratory Argon-CO₂ Mix for purchase comes from REAL GAZ with a certificate that states the composition, the uncertainty and the date of analysis, so it can be filed straight into your quality records.
Small cylinders are available for benches where space and consumption are modest.
Small cylinders are available for benches where space and consumption are modest.
Preparation follows ISO 6142-1, composition is cross-checked per ISO 6143, and documentation supports accredited and research laboratories working to ISO 17025.
Standard laboratory concentrations include 0.5%, 1%, 2%, 5% and 10% CO₂ in argon, though custom values can be requested. Each cylinder is supplied with a certificate showing the target value, the analysed value, the expanded uncertainty and the method used, and cylinders can be delivered with a stainless diaphragm valve and a CGA or DIN outlet as requested. Volumes of 2, 5, 10 and 20 litres are common and give from about 0.3 to 4 cubic metres of gas, sized for instrument calibration rather than bulk use.
Handle the cylinder with a clean, dry regulator, purge the connection before use and keep the cylinder at a stable temperature for several hours before calibrating, which lets the mixture reach equilibrium. Record the cylinder number in your logbook so any result can be matched to its reference gas during audits. If your accreditation body asks for traceability statements, tell us at the time of order and we will confirm which reference materials and methods stand behind the certificate you receive.
🏭 Where Laboratory Argon-CO₂ Mixtures Are Used
- 🔬 Instrument calibration — multi-point curves for non-dispersive infrared CO₂ sensors and thermal conductivity detectors;
- 🧫 Cell culture — verification of incubator CO₂ readings against an independent reference;
- 🧪 Plasma spectroscopy — argon plasma instruments that include a small CO₂ addition for particular sample matrices;
- 🎓 University teaching — student experiments in gas analysis that need a safe and defined mixture.
💡 Why Choose REAL GAZ
- ✅ Certificate included — a CoA states every component, the uncertainty and the traceability route;
- 🧪 Small cylinder formats — pay for the volume you use rather than a large industrial cylinder;
- 🎯 Matching concentrations — pick levels that bracket your instrument range for sound calibration;
- 🔒 Shelf-life guidance — validity period and storage advice are stated so you know when to retest.
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- certified balances for gravimetric work;
- chromatographic verification of the final mix;
- moisture analysis;
- valve leak testing before release.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
