DSW supplies high-quality liquid argon dewars and argon dewar bottles for the safe storage and transport of cryogenic gases, including liquid argon (LAr), liquid oxygen (LO₂), liquid nitrogen (LN₂), and CO₂.
Our argon storage dewars are manufactured from premium stainless steel and built to stringent international safety standards. The result is a durable, low-evaporation dewar argon solution suitable for industrial, medical, and laboratory applications.
Available in a range of argon dewar sizes, from small laboratory models to large industrial argon dewar tanks, these vessels ensure a a reliable gas or liquid supply for every requirement.
Key Features
- Multi-Layer Vacuum Insulation – Minimises heat ingress and evaporation.
- Stable Gas Supply – Integrated vaporiser provides continuous output.
- International Standard Valve System – Compliant with CGA/DIN/GB; premium imported Rego® valves available.
- Shock-Resistant Structure – Reinforced base and damping ring for safe transport.
- Digital Liquid Level Gauge (Optional) – Accurate monitoring of contents.
- Multiple Argon Dewar Sizes – Capacities from 80L to 1000L to suit all applications.
Types and Capacities
Argon dewars are available in a variety of sizes and pressure levels to suit different applications:
• Laboratory dewars (60–265L): Suitable for routine high-volume gas use.
• Industrial dewars (160–450L): Designed for heavier demand; microbulk options exceed 1000L for large-scale operations.
• Pressure ratings: Low, medium, and high pressure from 22 psi to 350 psi.
• Construction: Vacuum-insulated stainless steel with multi-layer insulation, welded structure, and integrated safety relief valves.

Tips
- Double-wall surfaces are silver-plated or polished to reduce heat radiation.
- Inner wall neck uses non-conductive material to minimise heat transfer.
