210L Liquid Nitrogen Dewar ndi chidebe chapamwamba cha cryogenic insulated chopangidwa kuti chisungidwe ndi kunyamula nayitrogeni wamadzimadzi.
Mapangidwe a Dewar Flask amitundu iwiri, omwe amachepetsa kusamutsa kutentha kuti apereke chitetezo chokwanira komanso kuteteza kutentha, ndiye maziko a ntchito yake.
Digiri ya vacuum ikabwezeretsedwa pamtengo wa fakitale, magwiridwe antchito a silinda ya gasi ya cryogenic amatha kusintha kwambiri.
Dewars ndi zombo zapadera za vacuum insulated zitsulo zosapanga dzimbiri. Amapangidwira kusungirako, kuyendetsa ndi kugwiritsa ntchito mpweya wamadzimadzi, nayitrogeni, argon kapena carbon dioxide.
