Description
Cylindrical Dewar flask, type 4C is a vacuum-insulated laboratory vessel intended for cold storage, cooling baths and dry-ice handling. It offers a nominal volume of 0,75 l with a slender cylindrical profile: inner diameter 57 mm, outer diameter 81 mm, inner height 310 mm and overall height 370 mm. A blue-coated metal casing surrounds the flask, adding mechanical protection for everyday laboratory use and transport between workstations. Net weight is approximately 0,8 kg and gross weight about 1,2 kg, so the unit remains manageable on the bench while providing greater working depth than smaller type variants. Delivered as one piece from manufacturer KGW Isotherm, type 4C is well suited to research, quality-control and teaching environments that need reliable thermal insulation together with a robust outer jacket. The extended inner height supports taller sample containers or larger coolant volumes, and the cylindrical geometry simplifies filling, retrieval and visual checks. Choose this format when a mid-to-larger capacity Dewar with consistent dimensions and durable metal cladding is required for routine cryogenic or dry-ice applications.

Questions about Cylindrical Dewar flask Typ 4C
What is this article?
Cylindrical Dewar flask Typ 4C 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.
