Description
Replacement glass 7 A is a spare glass insert for Dewar vessels of type 7 C and type 7 G. It restores the insulating glass body so that cryogenic liquids, dry ice and other low-temperature media can again be handled safely in the laboratory. The part is supplied as a single piece with a net weight of 0,8 kg and a gross weight of 0,8 kg, matching the geometry of the corresponding vessel types. Produced by KGW Isotherm, this replacement glass supports routine maintenance of Dewar and dry-ice container fleets without exchanging the complete outer assembly. Typical applications include temporary cold storage of samples, transport of cooling media and bench-top cryogenic work where vacuum-insulated glass performance is essential. By replacing only the glass element when vacuum integrity is lost or the insert is damaged, laboratories keep existing Dewar housings in service and reduce downtime. The component is classified among Dewar vessels and dry-ice containers and suits research, quality-control and industrial laboratory environments that rely on type 7 C and 7 G vessels.
This article is part of Cryo boxes, racks & freezer storage, in Cryogenics & cold storage.

Questions about Dewar flask glass refill for Typ 7 C & G
What is this article?
Dewar flask glass refill for Typ 7 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.
