Dewar Selection: Separate Body, Casing and Lid Temperature Limits
The inner vessel, casing, cushioning and closure may have different temperature limits. Equal capacity does not establish identical cryogenic holding performance.
View resource →Product overview
DSS/GSS stainless-steel Dewars support laboratory cooling and internal short-distance cryogen transport. They differ in side grips and carrying handles; 1000 W is the wide, low-profile version. Check capacity, dimensions, holding time and stopper for each type.
Key features
- Stainless-steel vessels combine insulation with convenient handling.
- GSS has a side grip; GSS 1000 and larger types also have a carrying handle. GSS 500 has no carrying handle.
- DSS 1000 and larger types have a carrying handle; DSS 500 does not.
- DSS/GSS 1000 W differs in opening and height from the standard 1000 type, while both hold approximately 1000 ml.
- Loose-fitting insulating stoppers are available by type; these are not pressure-tight lids.
- The datasheet gives −200 to +150 °C, briefly +200 °C; stopper limit +80 °C. Vessels operate without pressure.

Applications
Small-sample cooling, storage and internal short-distance transport of liquid nitrogen, dry ice and other cooling media, and insulated containment.
Selection guidance
Select capacity, opening, height and cryogenic performance, then choose DSS/GSS handle configuration. GSS 6000 technical data are supplemented from the manufacturer datasheet; match each order number and stopper.
