Description
Replacement glass 12 A is a spare inner glass insert intended for Dewar vessel types 12 C and 12 G. It restores the vacuum-insulated glass body of compatible Dewar flasks used for storing and handling cryogenic liquids or temperature-sensitive samples in the laboratory. The component is supplied as a single piece with a net weight of 1 kg and is manufactured for precise fit with the corresponding Dewar housings. Produced by manufacturer KGW Isotherm, this replacement glass supports continued safe operation of existing type 12 C and 12 G vessels when the original insert is damaged or worn. Suitable for laboratories working with liquid nitrogen, dry ice or other low-temperature media, it belongs to the Dewar vessel and dry-ice container product group. The unit is offered as one piece, allowing targeted maintenance without replacing the entire Dewar assembly. Origin is Germany, ensuring compatibility with the original KGW Isotherm design specifications for these vessel types.

Questions about Dewar flask glass refill for Typ 12 C & G
What is this article?
Dewar flask glass refill for Typ 12 C & G 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.
