Laboratory Liquid CO₂ Cylinder — analytical-quality liquid carbon dioxide in a bottle
A Laboratory Liquid CO₂ Cylinder from REAL GAZ contains carbon dioxide prepared for analytical work, with controlled moisture and trace organics.
Valves and internal surfaces are cleaned before filling, which reduces the risk of memory effects in sensitive detectors.

Cylinders conform to ISO 9809 and EN 1964, and the analysis supporting each lot follows ISO 17025 practice.
Choosing a Laboratory Liquid CO₂ Cylinder starts with the withdrawal mode. A dip-tube cylinder delivers liquid for cooling and supercritical pumps, while a standard cylinder gives gas for incubators and carrier-gas duties. Typical laboratory purities range from 99.99 per cent to 99.999 per cent, and each higher grade tightens limits on water, oxygen, nitrogen and total hydrocarbons. Connections follow the outlet standard used in your region, such as DIN 477 or CGA, and we can supply a matched stainless-steel regulator. Cylinders are delivered capped and upright, with the test date and net content clearly marked.
Good practice extends to the regulator. Purge the connection briefly before opening the main valve, use leak-test fluid on every joint, and close the cylinder valve at the end of the day. Stainless-steel diaphragm regulators and clean tubing protect the stated purity all the way to the instrument.

🏭 Where Laboratory CO₂ Cylinders Are Used
- 🧫 Cell culture — incubators hold 5 per cent CO₂ to maintain buffer chemistry in growth media;
- 📈 Chromatography — supercritical-fluid methods and cryogenic oven cooling depend on pure CO₂;
- 🌡️ Environmental chambers — plant-growth and climate chambers regulate carbon dioxide concentration precisely;
- 🧴 Sample extraction — analysts use dense CO₂ to pull lipids and flavour compounds from solids.
