Filtration is a common physical separation method in our daily life, which separates the mixture into different components through sieve, filter paper and other materials. In the chemical, biological and food industries, filtration is widely used to separate, purify and remove impurities.
The principle of
filtration experiment is to use different pore size and filtration speed of filter paper and other materials to filter out the solid particles and suspended substances in the mixture, so that they remain on the filter paper, while the solution enters the container through the filter paper. The separation of the mixture is thus achieved.

the specific experimental process, we must first choose the filter material suitable for the demand. Filter paper is divided into different pore size and speed levels, and different filter paper can achieve different filtering effects, so it is very important to choose the right filter paper material. In addition, the temperature and pressure of the liquid will also affect the filtering effect of the filter paper. It is necessary to ensure the stability of temperature and pressure in order to obtain accurate experimental data.

In daily life, filtration is widely used in beverages, pharmaceuticals, cosmetics and industrial products. For example, when making beverages, it is necessary to filter out impurities and solid particles mixed in them to obtain better taste and quality; when producing cosmetics and medicines, filtration can remove foreign impurities and impure substances to ensure product quality and safety; In industrial products, filtration can accelerate the process and improve production efficiency and quality.

filtration is a common separation method, and its experimental principles and applications play an important role in our daily lives. Through in-depth understanding of the principles and methods of filtration experiments, we can better apply them to practical work and improve work efficiency and production quality.
