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 seems so magical, and it is! Follow these rules when handling it to stay safe on Halloween however you use it: in drinks, punch bowls, and more.
An acetone/dry ice mixture cools many low-temperature reactions. [69] Make-up artists use acetone to remove skin adhesive from the netting of wigs and mustaches by immersing the item in an acetone bath, then removing the softened glue residue with a stiff brush. [ 70 ]
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.
