Dry ice has fewer problems with storage, since it can be generated from compressed carbon dioxide gas as needed. [25] In plumbing, dry ice is used to cut off water flow to pipes to allow repairs to be made without shutting off water mains.
Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.

Dry ice and water ice can be also used as coolants, when in direct contact with the structure being cooled. Sometimes an additional heat transfer fluid is used; water with ice and dry ice in acetone are two popular pairings. Sublimation of water ice was used for cooling the space suit for Project Apollo.
Make an enormous bubble out of dry ice in the comfort of your kitchen with these simple ingredients.
Antifreeze proteins bind to small ice crystals to inhibit growth and recrystallization of ice that would otherwise be fatal. [ 5 ] [ 6 ] Cryoprotectants are commonly used in cryobiology to prevent or inhibit freezing in sperm, blood, stem cells, plant seeds, etc. [ 7 ] [ 8 ] Ethylene glycol, propylene glycol, and glycerol (all used in ...
