Dewar cylinder for cryogenic storage and transport of liquid nitrogen and oxygen

Dewar cylinders, also known as cryogenic vessels or low-temperature cylinders, are specially designed for the safe storage and transport of liquefied gases, including liquid nitrogen, oxygen, carbon dioxide, and argon.
Engineered with advanced vacuum insulation and durable construction, these cryogenic cylinders minimize boil-off and maintain stable conditions, making them essential for laboratories, medical facilities, and industrial applications.

Category Overview

This category features a wide range of Dewar cylinders and cryogenic containers, from compact laboratory models to larger industrial liquid gas cylinders.
Each unit is designed for efficient thermal insulation, safe handling, and long-term reliability for storing cryogenic liquids.

Types of Dewar Vessels

Dewar vessels, also called Dewar containers, are specially designed for storing and transporting cryogenic liquids safely.
Different types of Dewars are suitable for different users, capacities, and liquids, including
liquid nitrogen (LN₂),
liquid oxygen (LO₂),
liquid carbon dioxide (LCO₂), and
liquid argon (LAr).
