Industrial Dewar Flasks for sale — robust cryogenic flasks built for the shop floor
REAL GAZ offers industrial Dewar flasks for sale with thick stainless-steel shells, protective guard rings and high-vacuum insulation, designed for repeated daily handling.
They suit plants that draw small volumes of liquid nitrogen or argon many times a shift and need a vessel that survives knocks and vibration.

Flask design references EN 13458 and ISO 21029-1, with material choices following ISO 21010 for cryogenic service.
In a factory, a flask lives a hard life: it is dragged across floors, filled quickly and often left open for hours. For this reason, industrial flasks use heavier gauge steel, welded neck rings and wide bases that resist tipping. Typical capacities run from 10 to 50 litres, and many users keep a spare so that a flask can be filled and rested while another is in service. We can suggest the number of flasks required for one, two or three shifts, based on your measured consumption of liquid nitrogen or argon. Workshops should also set aside a ventilated filling point, away from drains and pits, since cold gas is heavier than air and collects at floor level. Simple signs help new operators follow the same routine.
🏭 Where Industrial Dewar Flasks Are Used
- 🔧 Assembly lines — operators cool pins and sleeves in a flask before pressing them into housings;
- 🧪 Quality laboratories — impact testing at low temperature, such as Charpy tests, uses a conditioning bath held in a flask;
- 🚗 Automotive workshops — technicians chill valve seats and bearings for easy installation;
- 🧯 Plastics and rubber — deflashing and cryogenic trimming use controlled liquid nitrogen supply.
🏗️ Built for Plant Conditions
- steel guard ring and carrying handles protect the vessel body;
- castor bases on larger flasks allow movement across level floors;
- pressure-relief provision on closed-lid models prevents dangerous build-up.
💡 Why Choose REAL GAZ
- ✅ Durability — construction resists impact, vibration and frequent thermal cycling;
- 🧪 Low loss — a good vacuum keeps evaporation modest, so a filled flask lasts through the working week;
- 🎯 Fit for purpose — we advise whether an open-neck flask or a pressurised vessel is more efficient for your task;
- 🔒 Safe operation — lids, funnels and transfer tools are offered so staff avoid splashing and burns;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- multi-stage inspection of every vessel before filling;
- vacuum and insulation performance checks;
- moisture & impurity analysis of the filled liquid;
- leak testing and pressure integrity checks.
Vessels and refills respect ADR / UN rules and relevant EN/ISO standards, and operators should wear face protection and insulated gloves.
