Soxhlet extraction / Randall extraction / Twisselmann extraction

Extraction procedures (concretely: solid-liquid extraction process) are used to separated soluble components from a sold sample. In the lab, organic solvents such as hexane or petroleum spirit are often used as extractants. What all extraction processes have in common is that as many components as possible are to be separated with a defined quantity of solvent. This can be achieved by constantly evaporating the solvent and having it drip into the samples from a reflux cooler.
