Technical Liquid Nitrogen for laboratories — dependable cryogenic cooling for the working laboratory
Technical liquid nitrogen from REAL GAZ is a cold, colourless and inert cryogenic liquid that boils at −196 °C, and our Technical Liquid Nitrogen for laboratories range is prepared for research benches, teaching labs and analytical facilities that need steady cooling without chemical contamination.
Each delivery is drawn from air-separation production, checked for purity and moisture, and filled into insulated vessels sized for laboratory handling.

REAL GAZ supplies this product with reference to EN 13458 for static cryogenic vessels, ISO 21029 for transportable vacuum-insulated vessels and ISO 17025 practice for analytical checks, suitable for teaching, research and quality-control laboratories.
Handling and storage matter as much as purity. Keep vessels upright, in a ventilated room, away from sealed cupboards, and never close a cryogenic container with an airtight stopper. Wear a face shield, loose insulated gloves and closed shoes when decanting. Typical laboratory formats range from a few litres in a narrow-neck flask to 50 or 100 litre pressurised dewars, and our team will recommend the size that matches your daily draw and your lift capacity. Teaching laboratories in particular value a predictable weekly delivery, because it allows technicians to prepare demonstrations and practical classes without worrying about running short during term.
🏭 Where Technical Liquid Nitrogen Is Used
- ⚙️ Sample preparation — liquid nitrogen embrittles tough polymers, rubber and plant tissue so that they can be milled or ground to a fine, uniform powder;
- 🔬 Cold traps — vacuum lines, rotary evaporators and freeze-dryers use a nitrogen-cooled trap to condense solvent vapours before they reach the pump;
- 🏥 Biological storage — cryovials, cell lines and tissue samples are held in the vapour phase of nitrogen-cooled storage tanks for long-term preservation;
- 🚀 Materials testing — impact specimens and metal samples are chilled to a defined low temperature before ductile-to-brittle transition tests.
