When storing the Dewar flask, make sure it is placed in a well-ventilated, dry place away from direct sunlight, away from flammable materials and heat sources. The Dewar flask should be stored on a stable laboratory table or stand to prevent tipping or overturning. At the same time, the Dewar flask should be kept at a sufficient distance from other experimental equipment to avoid damage or tipping of the flask due to external impact.
During storage, the appearance of the Dewar flask should be checked regularly to see if it is intact, free of cracks, scratches and other defects, and whether the bottle cap is tightened and the sealing ring is intact. If any damaged or aged parts are found, they should be replaced in time to ensure sealing performance. In addition, the Dewar flask should be cleaned and maintained regularly, dust and stains on the surface should be removed, cleaned with detergent and appropriate tools, and rinsed with pure water.
