What is a Vacuum Filter Flask?
A vacuum filtering flask (Buchner or "Sand Core" type) is a type of laboratory glassware (labware) that is used for vacuum filtration. It consists of a flat-bottomed Erlenmeyer filter flask with graduated volume markings and a sidearm fitted with a vacuum adapter that allows for a vacuum pump to be attached.
The vacuum is applied to the lower flask, creating a differential pressure across the filter paper. This differential pressure caused the liquid to flow from the funnel, through the filter paper and into the lower flask The flask is used in conjunction with a funnel and Millipore filter paper to separate solid particles from liquids.

Where are they used?
Vacuum filtration is a widely used technique in scientific, chemistry and biology labs, as it allows for efficient and rapid separation of solid particles from a liquid. This technique is particularly useful when working with small amounts of samples, as it can help reduce the time needed for filtration and minimize contamination. When paired with an efficient vacuum source they become an indispensable laboratory tool.

What are they used for?
Vacuum filtration can be used for a variety of applications, such as separating cells or bacteria from a liquid culture, isolating compounds from a mixture, or removing impurities from a solution. The vacuum filter flask allows for a quick and efficient process of filtration, and the use of a vacuum pump ensures that the liquid passes through the filter paper evenly and without clogging.
