Laboratory Liquid CO₂ — high purity carbon dioxide for research
Laboratory liquid CO₂ from REAL GAZ is high purity carbon dioxide, normally 99.99 % or better, filled into carefully prepared cylinders for analytical and experimental use.
Low levels of moisture, hydrocarbons and sulphur compounds protect detectors, columns and sample integrity.
Low levels of moisture, hydrocarbons and sulphur compounds protect detectors, columns and sample integrity.
Product control follows ISO 17025 practice and purity is verified by methods consistent with ISO 14687 style analysis, for laboratory and research use.
🏭 Where Laboratory Liquid CO₂ Is Used
- ⚙️ Supercritical fluid chromatography — pure CO₂ is the main mobile phase in SFC, replacing large volumes of organic solvents;
- 🔬 Cell culture incubators — regulated CO₂ maintains pH in incubators for tissue and microbiology work;
- 🏥 Sample extraction — supercritical CO₂ extracts flavours, oils and active compounds for analysis;
- 🚀 Cryo-preservation support — liquid CO₂ chills sample blocks and trays for microtome and storage work.
📦 Laboratory Liquid CO₂: Grades, Cylinders & Handling
Laboratory work imposes stricter limits than industrial use because the gas contacts detectors and samples directly. Siphon cylinders are standard for SFC, where the pump needs liquid CO₂, and a pre-cooled pump head or inlet chiller improves flow stability. Incubator users normally take gas-phase cylinders with a two-stage regulator and an in-line sterile filter. Cylinder valves are fitted with the connector common for your instruments, and the internal surface is cleaned to reduce particles. Use stainless steel or PTFE-lined tubing for sensitive lines and purge them with the gas before starting. Consumption in laboratories is often low, so a single cylinder may last weeks, but a reserve cylinder prevents interruption of long experiments.
