IPA: /ˈkrɪs.tə.laɪ.zər/
KK: /ˈkrɪs.tə.laɪ.zər/
A container used in chemical engineering where a solution turns into solid crystals.
The scientist placed the solution in the crystallizer to form pure crystals.
Crystallizer → It is formed from "crystal" (from Greek "kristallos", meaning ice or frozen) and "-izer" (meaning to make or cause to become). The word "crystallizer" refers to something that causes the formation of crystals or makes something crystalline.
Think of something that 'makes' ('-izer') 'frozen' or 'ice-like' ('kristallos') — that's why a crystallizer is something that helps form crystals.
