What is a RotoVap

Rotovaps are particularly used for the creation of concentrated fruit juices, extracting brandy from wine, and concentrating coffee.

How are Rotovaps Used in Molecular Gastronomy?

Rotovaps are used in cooking for two main purposes, the first of which being the concentration of non-volatile components in a mixture, an example being concentrating the purest flavors in an orange. 

The second main rotovap use is to extract an aroma or flavor molecule from mixtures gently and at low temperatures, an example being extracting desired flavors from a mixture of alcohol, herbs and fruit without needing to heat the mixture up.
