Mapangidwe a Dewar Flask amitundu iwiri, omwe amachepetsa kusamutsa kutentha kuti apereke chitetezo chokwanira komanso kuteteza kutentha, ndiye maziko a ntchito yake.
Dewar Flask ndiye njira yabwino kwambiri yosungiramo mpweya wamadzimadzi komanso kuyesa kutentha kochepa.
Kuyang'ana nthawi zonse kulimba kwa botolo ndi mawonekedwe ake ndikofunikira kuti muwonetsetse kuti chidacho chilibe ming'alu, zokopa, kapena kusindikiza kosakwanira, zomwe zingalepheretse ma flasks a Dewar kuti asatayike.
Cryogenic storage dewars ndi ma vacuum flasks omwe amakhala ndi nayitrogeni wamadzimadzi kapena helium yamadzi (cryogen). Kusankha dewar yoyenera pa ntchito yanu ndikofunikira.
Botolo lamadzi la nitrogen dewar lamadzimadzi limapereka kutsekereza kolondola, kuwonetsetsa kusungidwa kotetezeka komanso kodalirika kwa nayitrogeni wamadzimadzi.
