Why is a Buchner funnel used instead of gravity filtration?
Vacuum filtration uses a Buchner funnel and a side-arm flask. Vacuum filtration is faster than gravity filtration, because the solvent or solution and air is forced through the filter paper by the application of reduced pressure. Add a Buchner funnel with a rubber funnel adaptor.
When and why is Buchner funnel used in crystallization procedure?
Vacuum filtration is used to collect crystals Vacuum filtration can be a fast process because the vacuum helps to rapidly pull the solution through the filter. When collecting crystals, a buchner funnel is used to collect the crystals while the solution is pulled out by the vacuum.9 Apr 2020

Why a Büchner funnel is used to isolate the final crystallized product?
It is used in organic chemistry labs to assist in collecting recrystallized compounds. The suction allows the wet recrystallized compound to dry out such that the pure dried crystal compound is left remaining.
How do you separate a precipitate from a solution?
The insoluble solid, called the precipitate, initially forms a suspension, meaning that it is well dispersed in solution. The precipitate typically agglomerates, and then is separated from the liquid by sedimentation, centrifugation, or filtration.
How does a Büchner funnel work?
A Buchner Funnel is a fritted/perforated funnel used in commercial laboratories for the vacuum-assisted filtration and separation of liquid substances. Buchner Funnels allow you to filter liquids by pulling them through qualitative filter paper and perforations in the top of the funnel using a vacuum pump.
