Plastic Funnels

WKM 56.55 Cubic Inches Capacity Porcelain Buchner Funnel with Fixed Perforated Plate KT34BF is a laboratory apparatus used for the process of vacuum filtration. It consists of a funnel-shaped glass or porcelain funnel with a perforated plate or a fritted glass disc at the bottom. The funnel is connected to a vacuum source through a sidearm or a rubber stopper, allowing for the application of suction to facilitate the filtration process.
The primary purpose of a Buchner funnel is to separate solids from liquids by using a vacuum to draw the liquid through the filter medium while retaining the solid particles on the filter surface. The filter medium can be a filter paper or a porous glass disc, depending on the nature of the sample being filtered. The perforated plate or fritted glass disc at the bottom of the funnel provides support for the filter medium and allows for the passage of the filtrate.
The use of a Buchner funnel offers several advantages over traditional gravity filtration. Firstly, it significantly speeds up the filtration process by applying suction, allowing for faster separation of solids and liquids. This is particularly useful when dealing with large volumes of liquid or when time is a critical factor. Additionally, the use of a vacuum reduces the risk of contamination as it minimizes the need for transferring the filtrate from one container to another.
To use a Buchner funnel, the filter medium is placed on the perforated plate or fritted glass disc, ensuring a tight seal. The sample to be filtered is poured into the funnel, and the vacuum source is turned on. The suction created by the vacuum draws the liquid through the filter medium, leaving the solid particles behind. The filtrate collects in a flask or container connected to the sidearm of the funnel.
Buchner funnels find applications in various scientific fields, including chemistry, biology, and environmental science. They are commonly used for separating precipitates from solutions, isolating solid compounds, and purifying samples. The versatility and efficiency of Buchner funnels make them an essential tool in many laboratory settings.
In conclusion, a Buchner funnel is a laboratory apparatus used for vacuum filtration. It consists of a funnel-shaped glass or porcelain funnel with a perforated plate or fritted glass disc at the bottom. The vacuum applied through a sidearm or rubber stopper allows for faster separation of solids and liquids compared to gravity filtration. Buchner funnels are widely used in scientific research and offer advantages such as increased filtration speed and reduced risk of contamination.
