Description
Stopper for Dewar insulation containers is a polyurethane (PU) cover intended for Dewar vessels with a volume of 8000 ml. The stopper lies loosely on top of the container, offering a simple, removable lid for everyday laboratory cooling and insulation work. It supports temperature-control setups where quick access to the vessel contents is required without a fixed seal. Supplied as a single piece from manufacturer KGW, the unit weighs 0,238 kg and is suited to Dewar flasks and related insulation containers used in research, analytical, and preparative laboratories. The loose-fit design helps limit evaporative losses and airborne contamination while remaining easy to lift and replace during sample handling or cryogenic procedures. This accessory fits within standard labware workflows for cooling vessels and temperature-control containers, providing a practical complement to large-volume Dewar systems. Clear dimensional matching to 8000 ml containers ensures straightforward selection for existing equipment parks.

Questions about Stopper f. Dewar-insulation containers, with vol. 8000ml, PU, lie loosely on top
What is this article?
Stopper f. Dewar-insulation containers, with vol. 8000ml, 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.
