DSW offers a full range of capacities from 20 litres to 425 litres in horizontal configurations, providing low evaporation loss, excellent thermal efficiency, and stable performance for laboratory, medical, and industrial applications.
What is LN2 storage dewar?
A liquid nitrogen storage dewar is a specialized vacuum flask that holds liquid nitrogen or liquid helium (cryogens).
These dewars are used for highly low-temperature storage in scientific, medical, and industrial applications.
The Dewar Ln2 offers extensive capacities and is built on a proven foundation. It can meet the needs for laboratory storage, fluid handling, and nitrogen handling.
These Dewars combine strength, high thermal efficiency, and ease of handling.
The Dewar Flasks have an all-stainless steel construction, including vacuum Dewar, to be rust-free, anti-corrosive, hygienic, and strong.
LN2 Dewar: These portable dewars are equally effective with liquid oxygen, liquid argon, liquid CO2, liquid helium and liquified gases. They can be used for both low-pressure transportation and storage.
These liquid nitrogen Dewars can fulfil many different applications. These are simple, efficient liquid nitrogen tanks that can also be used for liquid oxygen or argon.
Cryogenic Storage Dewars specification

Feature
Robust construction: The LN2 Dewars have been designed to handle the extreme temperatures that liquid Nitrogen can reach. They are made of materials that can withstand cold temperatures and prevent liquid Nitrogen from evaporating.
Safety features: LN2 storage Dewars are equipped with safety features such as differential pressure-type liquid level gauges, full trick vent valves, and relief devices that maintain the optimal pressure within the tank.
Mobility: Some cryogenic Dewars have casters, making it easy to move them around the laboratory.
Efficient storage: cryo LN2 Dewars are designed for efficient liquid nitrogen storage with low liquid nitrogen consumption.
Lightweight: Some LN2 Dewars have a wheeled platform, making them easy to move around the laboratory.
