Description
Cylindrical Dewar flask type 7C is a vacuum-insulated vessel intended for the safe handling and temporary storage of cryogenic liquids and cold samples in the laboratory. It offers a nominal volume of 1,2 l (1200 ml), an inner diameter of 67 mm and an outer diameter of 90 mm, with an inner height of 350 mm and an overall external height of 395 mm. The flask is enclosed in a robust metal jacket finished with a blue coating that improves mechanical protection during everyday use. This Dewar vessel from manufacturer KGW Isotherm is supplied as a single unit, with a net weight of 0,8 kg and a gross weight of 1,4 kg. Its cylindrical geometry provides stable bench placement and convenient access for sample transfer. The combination of generous internal capacity and compact outer dimensions makes the type 7C well suited for dry-ice work, liquid-nitrogen applications and other temperature-sensitive procedures where reliable thermal insulation is required in teaching or research environments.

Questions about Cylindrical Dewar flask Typ 7C
What is this article?
Cylindrical Dewar flask Typ 7C 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.
