Cryogenic Dewar Supplier — reliable vessels and liquid supply for ultra-low temperatures
A dependable cryogenic Dewar supplier does more than deliver a vessel: REAL GAZ provides the Dewar, the liquefied gas and the scheduled refill service that keeps your process running.
Our range covers liquid nitrogen, liquid argon, liquid oxygen and liquid helium service, with capacities and fittings selected for your site.

Vessels are selected to meet EN 13458, ISO 21029-1 and CGA P-12 handling practice, serving industrial and medical users.
Cryogenic liquids behave very differently from compressed gases. One litre of liquid nitrogen expands to roughly 690 litres of gas, so vessels must always be able to vent. A good supplier therefore checks relief valves, neck seals and level gauges at every exchange. REAL GAZ keeps a record for each vessel, including its last inspection date and gas service, which helps quality managers answer audits quickly. Customers can also request advice on alarm systems, oxygen depletion monitors and signage for rooms that contain large Dewars. Large sites sometimes combine several Dewars on a shared manifold, with a changeover panel that maintains continuous supply while one vessel is exchanged. We can review your layout and suggest a practical arrangement.
🏭 Where Cryogenic Dewars Are Used
- 🧬 Biobanks and IVF — large Dewars with racks hold cryovials for decades at about minus 196 °C;
- 🏭 Metal treatment — sub-zero conditioning of tool steel improves dimensional stability and wear life;
- 🧊 Cold chain research — pharmaceutical teams store cell lines, vaccines under development and reference standards;
- 🛰️ Aerospace testing — components are thermally cycled in liquid nitrogen to simulate extreme operating conditions.
🧭 Supply Model
- scheduled refills — a delivery rhythm set by your boil-off rate and consumption;
- emergency top-ups — a contact route for urgent liquid when a sample store runs low;
- vessel exchange — empty units collected and replaced, so you hold no idle inventory.
