Cryogenic Liquid CO₂ for laboratories — cold, clean carbon dioxide for research and testing
Cryogenic Liquid CO₂ for laboratories from REAL GAZ gives research teams a source of cold carbon dioxide that is easy to dose and consistent in quality.
Cylinders and low-pressure vessels are prepared with clean fittings, so no oil or particles enter sensitive instruments.
Cylinders and low-pressure vessels are prepared with clean fittings, so no oil or particles enter sensitive instruments.
Quality is verified using methods consistent with ISO 17025, and equipment follows EN 13458 for static cryogenic vessels and ISO 21029 for transportable ones.
In a laboratory, the real value of liquid carbon dioxide is controlled cooling without a refrigeration unit. A short burst from a dip-tube cylinder forms fine snow at about minus 78 °C, which can chill a sample block, trap volatile compounds or stabilise a column oven during fast temperature drops. Such work needs gas with low water and low hydrocarbons, otherwise ice or residues clog nozzles. REAL GAZ prepares Cryogenic Liquid CO₂ for laboratories in dedicated cylinders, recommends a nozzle and hose set, and explains how to vent safely in small rooms where carbon dioxide could accumulate.
Regular use calls for good routines. Record the cylinder weight at each change to predict consumption, install a CO₂ monitor near the point of use, and keep a spare cylinder for critical experiments. We can set up a standing delivery rhythm so the supply follows your experiment calendar rather than interrupting it.

🏭 Where Cryogenic Liquid CO₂ Is Used in Laboratories
- ❄️ Oven and column cooling — gas chromatographs use liquid CO₂ for sub-ambient starting temperatures;
- 🧬 Sample preservation — short-term cooling protects thermally sensitive tissue and reagent samples;
- 🧪 Freeze-drying support — CO₂ cooling assists pre-freezing steps before vacuum sublimation;
- 🔭 Materials testing — controlled cold exposure is used to study brittleness and thermal shock in polymers and metals.
