Description
Stopper for Dewar insulation containers provides a loosely seated cover for insulated vessels rated at 2500 ml working volume. Produced in PU, the stopper rests on the container rim without a tight seal, enabling quick access while helping to moderate heat exchange in cooling and temperature-control tasks. The unit is supplied as a single piece and has a weight of 0,145 kg. It is intended for laboratory Dewar-type insulation containers and related cooling vessels where a simple, removable top is more practical than a clamped or ground joint. Typical use includes chilled reagent holding, cold baths, and insulated sample work that benefits from reduced thermal load without permanent closure. This accessory from manufacturer KGW fits routine labware assemblies in research, quality-control, and instructional settings. Its loose-fit design supports repeated opening and closing during multi-step procedures, complementing Dewar flasks and temperature-control containers already in service on the bench.

Questions about Stopper f. Dewar-insulation containers, with vol. 2500ml, PU, lie loosely on top
What is this article?
Stopper f. Dewar-insulation containers, with vol. 2500ml, PU, lie loosely on top is the article on this page. Luminix Health distributes KGW 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.
