25-07-2019· 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.
This Filtration Kit allows rapid separation of mixtures via vacuum filtration. The stopper is cut to hold a Buchner funnel. The hand-operated vacuum pump simplifies vacuum filtration, eliminating the need for a water source or vacuum aspirator. It is more economical than an electric vacuum pump. The…
Vacuum Filters. We provide bottle-top vacuum filtration and pressure filtration units for routine filtration of buffers, solvents and culture media, syringeless filters for HPLC and UHPLC sample preparation, pressure filter funnels for solute and compound drying, and analytical filter funnels for microbiological testing.
A filter flask (sometimes called a Büchner or vacuum flask, suction flask, or even side-arm flask) is a piece of laboratory glassware with an attached hose barb for connecting a flexible hose/tubing or a vacuum pump/filtration pump for vacuum filtration.. Unlike some smaller, Erlenmeyer Flask varieties, this product is a larger format, carboy-style filtering flask.
Vacuum Gasket for Filter Funnels. Thermo Scientific Nalgene. Replace #7 or #8 stoppers in any manifold or filtering flask with the Thermo Scientific™ Nalgene™ Vacuum Gasket for Filter Funnels. Permits filter funnel to slide quickly and easily in and out of gasket.
When everything is tightly connected, turn on your pump. Pour the solution you wish to filter into the top of the funnel. Solids will be collected on top of the filter paper, and the filtered solvent will be captured in the filtering flask. Repeat as necessary until the desired purity is achieved. The vacuum creates a pressure differential.
When setting vacuum filtration, the first step is fitting the Buchner funnel to a suction flask. After that, we can connect the side arm of the flask to our vacuum pump which is of high quality, advanced design, and high efficiency. Next step is to put the filter paper into the funnel and wash it with the solution.

A Büchner funnel is a piece of laboratory equipment used in filtration. It is traditionally made of porcelain, but glass and plastic funnels are also available. On top of the funnel-shaped part there is a cylinder with a fritted glass disc/perforated plate separating it from the funnel. The Hirsch funnel has a similar design; it is used similarly, but for smaller quantities of material.

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. Do not use vacuum filtration to filter a solid from a liquid if it is the liquid that you want, and if the liquid is ...

Vacuum filtration is driven by negative pressure (from a vacuum pump, for example) applied downstream of the filter holder. The retentate on the filter's surface or the fluid filtrate can be collected for further analysis. Vacuum filtration is used primarily in microbiological and laboratory procedures involving the collection of a particulate ...
A Büchner flask, also known as a vacuum flask, filter flask, suction flask, side-arm flask, Kitasato flask or Bunsen flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck. The short tube and hose barb effectively act as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to ...
