A filtration flask, also known as a filtering flask, is a type of laboratory flask that has a flat bottom and a cylindrical neck with a ground glass joint. They are typically made of borosilicate glass, which is heat-resistant and can withstand high temperatures and pressures.

They are commonly used in chemistry and biology labs for filtering liquids and solutions. They come in a variety of sizes, with commonly used sizes ranging from 50 milliliters to 1000 milliliters. They have a sidearm tube, the arm is usually at 90-degree angle to the flask, which is used to connect the flask to a vacuum pump.

This feature allows for a more efficient filtration process by creating a vacuum in the flask, which pulls the liquid through the filter and into the flask. They can be used with a variety of filter funnels, filter papers, and filter holders to separate solids from liquids. They are also easy to clean and can be used multiple times.
