Technical Liquid Gas Cylinders for Laboratories

Technical Liquid Gas Cylinders for laboratories — compact liquid supply for benches, cold rooms and instruments

Technical liquid gas cylinders for laboratories let a research group hold a large gas volume in a small footprint. REAL GAZ supplies low-pressure cryogenic liquid cylinders in compact sizes, with gas-use, liquid-withdrawal and combined outlets for nitrogen, argon, oxygen and carbon dioxide.
Because one litre of liquid expands to several hundred litres of gas, a single cylinder can run an instrument for weeks without a swap.

The vessels are vacuum insulated and built in line with EN 1251 and ISO 21029-1, with valves to EN ISO 10297 and colour identification following EN 1089-3.

🏭 Where Laboratory Liquid Gas Cylinders Are Used

⚙️ Cell culture and biobanking — liquid nitrogen cylinders refill storage freezers and cryo-tanks that preserve samples at around −196 °C;
🔬 Chromatography — gas-use outlets deliver clean nitrogen and argon for GC carrier, make-up and detector lines;
🏥 Materials testing — liquid nitrogen is used to cool specimens before impact tests and shrink-fit procedures;
🚀 University teaching — small vessels demonstrate cryogenic behaviour safely, with a documented gas grade for each practical.

💡 Why Choose REAL GAZ

✅ Low working pressure — typical relief settings are modest, so laboratory handling is simpler than with high-pressure steel cylinders;
🧪 Long hold time — good insulation keeps the contents for days, ideal for intermittent bench use;
🎯 Right-sized vessels — we advise on capacity so that you do not buy more liquid than you can use before boil-off;
🔒 Clear labelling — product name, UN number, hazard pictograms and lot number are marked on each cylinder.
📄 Certificate of Analysis (CoA) — supplied with every order.

📦 Handling & Storage of Laboratory Liquid Gas Cylinders

Place cylinders on a level floor in a well-ventilated room; oxygen monitors are advised in confined spaces.
Use only transfer hoses rated for cryogenic service.
Do not tilt the cylinder or block the vent; frost on the outlet is normal during liquid draw.
Estimate demand by instrument: a gas chromatograph, a freezer top-up and a glovebox each draw very different volumes, so list them before choosing a size.
Choose a gas-use outlet for continuous supply and a liquid-withdrawal outlet for filling Dewars or cryo-tanks; combined vessels serve both.
Request a written safety briefing for new staff, covering oxygen monitoring, cold-burn first aid and emergency ventilation.
Plan exchanges before the contents gauge reaches the lower mark, because pressure-building performance falls as the vessel empties.

🔬 Quality Control & Safety

gas purity verification before filling;
vacuum and relief device inspection;
tare and fill-weight checks on every vessel;
leak testing of valves and couplings.

Each cylinder is filled and transported under ADR / UN requirements and inspected on return.
