 Specifications

• Dewar Material:  silvered and vacuum pumped borosilicate glass,
• Container Material:  satin finish stainless steel,

• Holding time: 
• Approximate and relative to usage. 
• Intended only to provide a comparison of times for a Dewar with lid to empty completely after 90% fill with Liquid Nitrogen (LN2).
• This time will vary with ambient temperatures, frequency of lid removal, handling of contents, and the mass of the material being frozen.
• Vapor Phase: Dewars may be used as vapor phase storage while almost empty of Liquid Nitrogen.  Liquid Nitrogen will boil off to become a very low temperature gas and the Dewar with lid on will hold vapor phase nitrogen gas at temperatures of -160^oC to -140^oC. 
• Dry Ice (Frozen solid CO2): 
• Used with dry-ice (solid CO2) the Dewar will maintain temperature of approximately -90^oC.
• Holding times for CO2 are about 25% longer than those listed above for LN2.
