Distillation is a simple process that is used to separate pure liquids from liquid mixtures. Because distillation relies on boiling away liquid substances, only mixtures with substances with distinctively different boili... More »

Bitumen is primarily used to pave roads. It is a brown or black mixture of hydrocarbons, which is derived from petroleum. The consistency of bitumen varies from viscous to solid, and in its solid form, it is commonly kno... More »

Distilling flasks are glass flasks used to separate mixtures by distillation. A distillation flask has three parts: a spherical base, a cylindrical neck and sidearm that is connected to the flask neck. Distillation is th... More »

A rotary evaporator, or rotavap, works by heating liquids under low pressure, vaporizing them and condensing that gas in a separate vessel, just like many other distillation apparatus. However, a rotavap uses both temper... More »

Extraction, distillation, recrystallization and chromatography are different chemical methods of separation. Extraction is useful for separating compounds with different polarities, and distillation is commonly used to p... More »

Food producers use distillation as a way to purify water by boiling it, then collecting the steam and cooling it so it condenses into a purified product. Oil refineries use fractional distillation to separate petroleum i... More »
