Description
Cylindrical Dewar flask, type 5C is a vacuum-insulated vessel with a nominal volume of 1,25 l for low-temperature laboratory work and dry-ice handling. The flask offers an inner diameter of 57 mm, an outer diameter of 81 mm, an inner height of 500 mm and an outer height of 550 mm. It is supplied with a blue-coated metal protective casing that improves mechanical robustness during routine use. Net weight is 1,3 kg and gross weight is 1,8 kg. Designed as product type 5C, this cylindrical Dewar is suitable for storing and transporting cryogenic media or dry ice in research, analytical and industrial laboratories. The unit comes as a single piece from manufacturer KGW Isotherm and originates from Germany. Clear dimensional data allow straightforward integration into existing cold-storage workflows and compatibility checks with lids, racks or transfer tools. The flask addresses typical requirements for Dewar vessels and dry-ice containers where a defined internal geometry and protective outer jacket are needed.

Questions about Cylindrical Dewar flask Typ 5C
What is this article?
Cylindrical Dewar flask Typ 5C is the article on this page. Luminix Health distributes KGW Isotherm for laboratory use. It sits in Cryo boxes, racks & freezer storage, inside Cryogenics & cold storage, in Lab consumables.
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.
