LHe Cylinder Supplier — cryogenic containers filled, tested and delivered
As an LHe cylinder supplier, REAL GAZ provides liquid helium in the vacuum-insulated containers that customers often call cylinders. Unlike high-pressure gas cylinders, these vessels hold the liquid at near-atmospheric pressure inside a double wall with deep vacuum.
We look after filling, inspection and transport so the container arrives cold, full and ready for transfer.

Vessels follow ISO 21029, EN 13458 and EN 1251, with valves to EN 1626, for medical equipment and research users.
Our container fleet is maintained on a regular inspection cycle. Technicians check vacuum retention, look for frost patches that indicate insulation failure, test the safety valves and burst discs, and confirm that the transfer fitting suits the customer. Containers that fail any check are withdrawn. Where a customer owns its dewars, we fill and certify them after the same inspection, so your own equipment is not a weak point.
Vessel size is a practical choice. A 100 L dewar passes through most doors and lifts, a 250 L unit suits steady consumers, and a 500 L container fits sites with a loading dock. Each type has a different boil-off rate and hold time, and we help you select the size that wastes the least helium for your usage pattern.
