filtrát

Filtrát is a term used in various scientific and technical contexts to describe the liquid that has passed through a filter. The process of filtration involves separating solid particles from a liquid or gas by passing the mixture through a porous medium, known as the filter. The filtrate is the component that successfully passes through this filter.

In chemistry, filtrate is the liquid obtained after a filtration process, such as removing precipitates from a solution. This filtrate can then be further analyzed, reacted, or purified. In biology, filtrate can refer to the liquid that has passed through a biological filter, for example, in dialysis or during the preparation of sterile solutions. The concept is also relevant in environmental science, where rainwater percolating through soil and rock can be considered a filtrate, carrying dissolved substances. The composition of the filtrate depends entirely on the original mixture and the type of filter used, as different filters have varying pore sizes and selectivities.
