<P> A cooling bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 ° C and − 196 ° C. These low temperatures are used to collect liquids after distillation, to remove solvents using a rotary evaporator, or to perform a chemical reaction below room temperature (see: kinetic control). </P> <P> Cooling baths are generally one of two types: (a) a cold fluid (particularly liquid nitrogen, water, or even air)--but most commonly the term refers to (b) a mixture of 3 components: (1) a cooling agent (such as dry ice or water ice); (2) a liquid' carrier' (such as liquid water, ethylene glycol, acetone, etc .), which transfers heat between the bath and the vessel;; and (3) an additive to depress the melting - point of the solid / liquid system . </P>
