An insulated flask used for carrying cryogenic liquids.
Originally made from glass in the same way as vacuum flasks, industrial dewars are usually made of metal insulated with expanded polystyrene to make them more robust.
Dewar flasks are named after Sir Edward Dewar who discovered in the late 1800s how to make liquid gases and store them.
