Dewar Cylinders for Cryogenic Liquids

Dewar Cylinders, also known as Cryogenic Dewars, are essential containers for storing and transporting cryogenic liquids such as nitrogen, oxygen, argon, and carbon dioxide (CO₂). Designed to maintain ultra-low temperatures, these vessels ensure the safe and efficient handling of sensitive cryogenic substances.

Types of Dewars

Type	Description	Typical Use
Storage Dewars	Long-term cryogenic storage with minimal evaporation loss	Laboratories, hospitals, industrial storage
Transport Dewars	Reinforced design for safe handling and mobility	Gas distribution and logistics
Self-Pressurizing Dewars	Internal pressure system enables controlled liquid withdrawal	Continuous or controlled supply applications
Open Neck Dewars	Wide opening for easy access to cryogenic liquids	Biological storage and laboratory research
Closed Neck Dewars	Sealed design reduces heat ingress and evaporation	Long-term storage and sensitive applications
Cryogenic Liquid Cylinders (CLCs)	High-capacity storage with integrated dispensing system	Industrial gas supply systems
