Buchner flask

A Buchner flask is a specialized laboratory glass container used in filtration processes. It has a sidearm that connects to a vacuum source, allowing air to be removed and speeding up the filtering of liquids through a filter paper or membrane placed inside the flask. This setup helps separate solids from liquids efficiently, especially in scientific or industrial work. The flask's sturdy construction and vacuum connection make filtering faster and more effective than traditional gravity-based methods, making it a common tool in chemistry and biology labs for purifying samples.
