When using a Buchner funnel, generally put a filter paper on the bottom of the cylinder, insert the funnel into the opening above the Buchner flask and seal the interface (for example, with a rubber ring). The side mouth of the Brinell beaker is connected with a suction system. Then, the solid and liquid mixture to be separated is poured into the upper part, and the liquid component is drawn into the beaker under the negative pressure, and the solid remains on the upper part. Commonly used in organic chemistry experiments to extract crystals. After filtering in this case, you can also use a small amount of pure solvent to wash away impurities on the crystal surface.
