Cryogenic Dewar Flasks for purchase — a clear route from enquiry to delivery
Customers who want cryogenic Dewar flasks for purchase can order directly from REAL GAZ, with guidance on model, capacity and first fill.

Specifications reference EN 13458, EN 1252-1 toughness requirements and ISO 21029-1, for commercial and scientific buyers.
Buying a flask is easier when the specification is simple. Static holding time tells you how long a filled flask keeps its liquid when closed; a good 10 litre unit may hold for several weeks, while a wide-neck 2 litre unit may last only a few days. Weight matters too, because a full 25 litre flask can exceed 30 kilograms. REAL GAZ lists these facts in each quotation and can propose a trolley for heavier models. After delivery, our team remains available if you need to arrange refills, repairs or a change of capacity. Public bodies and universities often need a formal quotation with technical sheets for procurement files. We can prepare these documents in the format your purchasing department prefers.
