Filtrate is a term used in various scientific and technical contexts, generally referring to a liquid that has passed through a filter. The process of filtration separates solid particles from a liquid or gas. The liquid or gas that passes through the filter is called the filtrate, while the solid material retained on the filter is known as the retentate or residue.

In chemistry, filtration is a common method for purifying liquids or separating precipitates from solutions. For example, when a solution containing a solid precipitate is filtered, the filtrate will be the clear liquid free of the solid particles. In biology and medicine, filtrate plays a crucial role in processes like hemodialysis, where waste products are filtered from the blood to produce a filtrate.

The composition of the filtrate depends entirely on the nature of the original mixture and the type of filter used. Filters are designed with specific pore sizes, allowing them to retain particles above a certain dimension while permitting smaller molecules and liquids to pass through. Therefore, the filtrate will contain all components of the original mixture that are smaller than the filter's pore size. The concept of filtrate is fundamental to understanding separation techniques across many disciplines.
