Vacuum filtration is a process used in chemistry labs to separate a solid from a liquid using a vacuum. This method is particularly useful when the solid and liquid are in a mixture and the solid needs to be collected for further study or use. However, vacuum filtration is also known by another name, which is ‘Buchner filtration’.
The Buchner funnel is named after Ernest Buchner, a German chemist who invented it in the late 1800s. The funnel is made of porcelain or glass and has a perforated plate on the bottom that allows the liquid to pass through while retaining the solid. The Buchner funnel is an essential part of vacuum filtration, as it helps the filtration process to proceed smoothly and efficiently.
When performing vacuum filtration, the Buchner funnel is placed on top of a filtering flask. The solid-liquid mixture is poured into the funnel, and the vacuum is turned on. The filtrate passes through the perforations in the plate and is collected in the filtering flask, while the solid remains in the funnel. Once all the liquid has passed through, the solid is removed from the funnel and dried for further use.
Buchner filtration is widely used in chemistry labs and has many applications. For example, it can be used to separate crystals from a solvent, to collect precipitates, or to purify a substance. It is particularly useful for tasks that involve large quantities of solid material or when the solid is not readily soluble in the liquid.
Buchner filtration is often preferred over other filtration methods because it is faster, more efficient, and produces a purer solid. In addition, it is relatively easy to set up and operate. However, there are some drawbacks to this method. For example, the Buchner funnel can become clogged if the solid is too fine or if the mixture has a high viscosity. If this happens, the vacuum needs to be turned off, and the perforations in the plate need to be cleaned before filtration can continue.
In conclusion, vacuum filtration is an essential technique in chemistry, and Buchner filtration is another name for it. The Buchner funnel is a crucial component of vacuum filtration, as it allows the solid to be collected while the liquid passes through. Buchner filtration is fast, efficient, and produces a purer solid than other methods. However, it is not without its challenges, and users need to be mindful of the potential for clogging. Overall, Buchner filtration is a reliable and widely used method for separating solids from liquids in chemical labs.

Frequently Asked Questions about Another Name for Vacuum Filtration
What is vacuum filtration?
Vacuum filtration is a laboratory technique used to separate a solid from a liquid using a vacuum filter. The method involves adding the mixture into a funnel equipped with a vacuum, which then draws the liquid through the filter and leaves the solid material behind.
What is another name for vacuum filtration?
Another name for vacuum filtration is Buchner filtration. The technique is named after the German chemist Ernst Buchner who first described the process in the late 19th century.
What are the applications of vacuum filtration?
Vacuum filtration is used in a variety of fields such as chemistry, biology, and environmental science to separate solids from liquids. It is commonly used in wastewater treatment, purification of compounds, and collection of microorganisms from liquid cultures.
What are the advantages of using vacuum filtration?
Vacuum filtration is a fast and efficient method for separating solids from liquids. It is less time-consuming than other common separation techniques such as sedimentation or decantation. Additionally, vacuum filtration can achieve a higher degree of separation, making it an ideal choice for applications where high purity of the separated solid is needed.
