This fluted paper offers a large surface area for efficient filtering. when doing hot gravity filtrations, since a narrow stem will often plug up with precipitated solids. In contrast, to collect a solid product, the usual choice is vacuum filtration.
Vacuum filtration uses either a Buchner or a Hirsch funnel. Vacuum Column chromatography in chemistry is a method used to purify individual chemical It is often used for preparative applications on scales from micrograms up to kilograms. A solution of the organic material is pipetted on top of the stationary phase.
