Suction filtration is a chemistry laboratory technique which allows for a greater rate of filtration. Whereas in normal filtration gravity provides the force which draws the liquid through the filter paper, in suction filtration a pressure gradient performs this function. This has the advantage of offering a variable rate depending on the ...

Vacuum filtration is a technique for separating a solid product from a liquid. The mixture of solid and liquid is poured through a filter paper in a Buchner funnel. The solid is trapped by the filter and the liquid is drawn through the funnel into the flask below, by a vacuum. "Vacuum filtration." Croatian-English Chemistry Dictionary ...
Vacuum Filtration technique is most preferred for small batch of solution in order to quickly dry out small crystals. This method requires a Büchner funnel, filter paper of smaller diameter than the funnel, Büchner flask, and rubber tubing to connect to vacuum source.

On the opposite hand, some sort of applied pressure, or a pressure differential created by the existence of a vacuum, can force the liquid through the filter. Gas filtration is employed in a common appliance, the vacuum cleaner, which passes a stream of dust-filled air through a filtering bag inside the machine.
Vacuum filtration uses a Buchner (pronounced "byook-ner") funnel and a water aspirator assembly. A Buchner funnel is a flat bottomed, porous, circular porcelain bowl with a short stem. The stem is fitted with a rubber stopper and inserted in the mouth of a side arm filter flask.
Adapters 89049-144 and -146 have a 2mm PTFE stopcock between the outer and inner joints to control vacuum source. Adapters with heavy duty tooled flare top are for reduced pressure filtration with plain stem buchner funnels, and accept pluro stopppers (not included). Adapter 89049-156 has a 20-400 GPI threaded top for transfer from vial to vial.
Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product. In
Vacuum and pressure pump: For use in the fields of microbiological quality control, analyses, medicine and production technology. The pump is used for pumping gases, taking samples (even liquids in a vacuum) and evacuating vessels.

Whatman™ Glass Vacuum Filtration Device Produced from borosilicate glass and suitable for aqueous and organic solvent filtration. The funnel seal ensures that the sample does not bypass the membrane and that particulates are retained on the surface of the membrane.
Filtration is a technique used to separate a solid from a liquid and is used in many experiments. Though filtration can be done simply with gravity, more often vacuum filtration is employed because it is much faster. Several points are worth remembering. First, be sure to clamp your filter flask ...
the Critical Process Filtration technologies that may be applied in chromatography systems at the end of this guide. Figure 1 below represents a generic system to feed and clean a single chromatography column. As stated above, a biopharmaceutical process may have many columns, so there may be a series of these systems in a single biotech process.
