Dewar flask

Dewar flask is an ideal container and tool for storing liquid gas, cryogenic research and crystal element protection. Glass Dewar bottles, due to their good thermal insulation properties, have been widely used in scientific research, medical care, oil drilling and other related fields. Glass Dewar has unique advantages over metal Dewar due to its simple structure, good thermal insulation performance, transparency and good sealing. However, glass is a brittle material with poor strength and fragile, so it is not suitable for manufacturing diameters larger than 250mm. ,700mm long Dewar flask. The volume of the spherical Dewar flask should not exceed 10,000ml. For users’ reference when designing.
