Vacuum Filtration- How do I secure the funnel to the flask?

Vacuum filtration, sometimes known as Buchner filtration is used to isolate a solid product or impurity from a liquid filtrate. Any solid product or impurity can be left on the filter paper present within the funnel and easily removed, whilst the filtrate passes through the funnel into the flask at the bottom, to be used further or discarded. Whilst the set-up can be considered simple in itself...

Since vacuum can be expressed in so many different units (mbar, bar, Torr, mm Hg, Pa, psi...) this can be difficult to do! Looking at the ultimate vacu...

What equipment do I need to perform a vacuum filtration?

Filtration under vacuum, also known as Büchner filtration, is commonly used to isolate the solid precipitate from a solution. This technique is used in syntheses, for example when a reaction has yielded a solid, or in analyses including gravimetric analysis of suspended solids. Although performing the filtration is simple, several pieces of equipment are needed which must all fit together, so...

Sintered disc or sintered frit filtration funnels - how to care for sintered discs? When to select a sintered disc funnel? What do sintered disc grades mean?

Vacuum filtrations using a Buchner flask and funnel with a vacuum pump are commonly used to isolate a solid of interest from a liquid. Most commonly a porcelain Buchner funnel with a filter paper placed on top is used, but in some instances a sintered disc funnel is more appropriate. But when would you select a sintered disc funnel? And how should a sintered disc filter funnel be cleaned ...
