Description
Replacement glass 4 A for Dewar vessel type 4 C & G is a spare inner glass insert intended for matching laboratory Dewar vessels used with cryogenic media and dry ice. This component restores the insulating glass body when the original vessel glass is damaged or worn, supporting continued low-temperature storage and handling in research and routine lab settings. Supplied as a single piece with a net weight of 0,8 kg and a gross weight of 0,8 kg, it is specified for Dewar vessel types 4 C and 4 G. The part originates from manufacturer KGW Isotherm and fits established laboratory workflows involving Dewar vessels and dry-ice containers. Its role is purely as a like-for-like glass replacement, helping maintain thermal performance and operational readiness of existing equipment without altering vessel geometry. Laboratories that already operate the corresponding type 4 C or 4 G vessels can use this glass to extend service life and keep cryogenic containment reliable for sample cooling, temporary storage, and related applications.

Questions about Dewar flask glass refill for Typ 4 C & G
What is this article?
Dewar flask glass refill for Typ 4 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.
