Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation. A large variety of equipment is utilized to perform distillations in a laboratory setting.

Types of Distillation
Simple Distillation
Simple distillation is a process in which vapors from the boiling flask are directly fed into the condenser. This process is primarily used to separate mixtures of liquids with significantly different boiling points.
Fractional Distillation
In fractional distillation, the vapors are fed through a fractionating column before entering the condenser. Cycles of vaporization and condensation within the column improves separation and allows liquids of much closer boiling points to be separated.
Vacuum Distillation
A vacuum distillation is any distillation conducted under reduced pressure. Reducing the pressure lowers the boiling points of the liquids in the mixture, allowing high-boiling mixtures to be easier to separate.
Flasks
Flasks are commonly used for both the boiling vessel and receiver. Several types of flasks are listed below:
