Cryogenic Liquid Propane for laboratories — low-temperature propane for research benches
Cryogenic liquid propane for laboratories from REAL GAZ is high purity propane supplied for low-temperature research, where its boiling point of about −42 °C at atmospheric pressure is put to scientific use.
Laboratory grade propane is dried and filtered so that trace water and heavier hydrocarbons do not disturb cold-trap, refrigeration or condensation experiments.
Laboratory grade propane is dried and filtered so that trace water and heavier hydrocarbons do not disturb cold-trap, refrigeration or condensation experiments.
Gas quality follows analytical practice under ISO 17025, while refrigeration use refers to ISO 817 (R-290) and EN 378, for laboratory and research users.
🏭 Where Cryogenic Liquid Propane Is Used
- ⚙️ Cold traps and condensers — liquid propane provides a moderate cooling stage for trapping volatile solvents and condensing vapours;
- 🔬 Refrigeration research — R-290 propane cycles are studied for heat pumps and small chillers as a low global warming refrigerant;
- 🏥 Thermodynamic studies — vapour pressure, density and phase behaviour measurements use pure propane as a well-characterised fluid;
- 🚀 Sample preparation — low-temperature extraction and fractionation of volatile organic compounds can use propane as the working fluid.
📦 Cryogenic Liquid Propane: Grades, Cylinders & Handling
Propane boils at about −42 °C at normal pressure, so it can be handled as a cold liquid in suitable equipment or as a pressurised liquid at room temperature. Because it is flammable, laboratories must treat it as a hazardous substance: only small quantities should be held in the room, apparatus must be earthed and non-sparking, and any exhaust should be taken to a safe place. Purity of 99.95 % is typical for research work, and a dip-tube cylinder is available when liquid is to be drawn directly. Pressure regulators, valves and tubing must be compatible with hydrocarbons and rated for the pressure involved. Please describe your experiment and our engineers, who supply cryogenic liquid propane for laboratories every month, will suggest a suitable arrangement.
💡 Why Choose REAL GAZ
- ✅ High purity — tightly controlled impurity limits give reproducible results from experiment to experiment;
- 🧪 Dry gas — low water content avoids ice formation and blocked lines at low temperature;
- 🎯 Suitable cylinders — dip-tube or vapour withdrawal valves can be specified according to how the liquid is drawn;
- 🔒 Safety guidance — our advisers explain flammable-gas rules for laboratory rooms and fume cupboards;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- purity analysis by gas chromatography;
- moisture content measurement;
- careful cleaning of cylinders and valves;
- leak testing before every dispatch.
Wear cold-resistant gloves, eye protection and keep ignition sources away when liquid propane is handled. Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
