Product Description
These Day-Impex DILVAC Glass Dewar flasks have blue enameled steel casings with handles and lids. They offer a lower cost alternative to the stainless steel range form and fit inside and out to the DILVAC stainless steel cased borosilicate glass dewar flasks. These are ideally suited for longer term transportation of liquids and specimens.
Applications

- 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 -160oC to -140oC.
- Dry Ice (Frozen solid CO2):
- Used with dry-ice (solid CO2) the Dewar will maintain temperature of approximately -90oC.
- Holding times for CO2 are about 25% longer than those listed above for LN2.
