Filtrate - GCSE Biology Definition

Filtrate is the liquid that has passed through a filter, leaving behind any solid particles that were mixed in with the liquid. In biology experiments, filtration is often used to separate solids from liquids using a material that acts like a sieve, such as filter paper. When you pour a mixture of solid and liquid onto the filter paper, the liquid part that flows through is called the filtrate. This process is important for separating substances and is commonly used in laboratories to study or clean up mixtures.
