Description
Set of Dewar vessels suitable for a double cold trap delivers dependable cryogenic containment for laboratory cooling and condensation work. These vessels support stable low-temperature operation in vacuum lines and cold-trap assemblies frequently employed in organic synthesis, solvent recovery and analytical sample preparation. The complete set integrates directly with matching double cold-trap configurations, ensuring secure thermal insulation and reduced boil-off during extended runs. Produced under the KGW ® registered trademark and supplied by manufacturer Rettberg, the assembly combines proven glassware design with practical laboratory handling. Net weight is 1,800 kg, giving a solid yet manageable unit for bench-top or fume-hood installation. Originating from Germany, the product type is classified as a Dewar vessel and belongs to the cold-trap category, making it a focused accessory for researchers who require reliable cryogenic performance without complex custom glassblowing. The set simplifies setup of double cold traps and contributes to consistent experimental results when handling condensable vapours or cryogens.

Questions about Set of Dewar vessels
What is this article?
Set of Dewar vessels is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Cryo boxes, racks & freezer storage, inside Cryogenics & cold storage, in Consommables.
A cryo box or a freezer rack is how vials are found again at −80 °C or in the vapour phase of nitrogen. The grid, 9×9 or 10×10, has to match the vials. A cardboard box and a polycarbonate box differ in whether they survive liquid nitrogen. The map of the box is part of the sample.
Cold storage slows chemistry and keeps cells, proteins and nucleic acids from falling apart. A cryogenic vial is made to survive liquid-nitrogen temperatures and to be sealed against the liquid. A box and a rack are how those vials are found again. The article is not part of free standard delivery when it must stay cold: cold-chain goods are never included in that free delivery. Biosafety of the material inside is summarised by the WHO laboratory biosafety topic. Reference lines are held by ATCC.
