Also called solvent extraction, a mixture of two components is treated by a solvent that preferentially dissolves one or more of the components in the mixture. The mixture so treated is called the raffinate and the solvent-rich phase is called extract. In extraction of solids, or leaching, soluble material is dissolved from its mixture .

Vacuum Filtration - Lab Society

Since the glass and products used will be subjected to pressure in vacuum filtration, make sure that the glass you use can withstand it. We recommend high quality, borosilicate glass for the task. The filter paper itself will reduce the system flow rate, so vacuum (or suction) filtration is performed to increase the flow rate and reduce filtration time.
