Vacuum filtration

When a solid needs to be isolated from a solution it is normally done at a reduced pressure using a Buchner flask and Buchner funnel. Video: Vacuum filtration video
Resource
Hot gravity filtration

This is the simplest kind of filtration when the solution to be filtered is poured through a filter paper in a filter funnel. The filtration of hot solutions through a funnel and fluted filter paper is often carried out as part of a recrystallisation. Gravity filtration is generally carried out ...
