cryophorusn.

Brit.

/krʌɪˈɒf(ə)rəs/, U.S.

/kraɪˈɑf(ə)rəs/

Origin: Formed within English, by compounding. Etymons: cryo- comb. form, electrophorus n., pyrophorus n.

Etymology: < cryo- comb. form + -phorus (in electrophorus n., pyrophorus n., etc.; compare quot. 1813).

An instrument for demonstrating the freezing of water by evaporation, invented by W. H. Wollaston (cf. Wollaston n.).The cryophorus consists of a short glass tube with a right-angle bend at each end terminating in a bulb. The apparatus is evacuated except for a small amount of water in one of the bulbs. When the empty bulb is immersed in a freezing mixture or a liquefied gas, the resultant cooling causes a drop in pressure and so more evaporation of the water, which soon freezes.
