What is Filter Paper?

The filter paper for laboratory use is one of the common lab consumables. It is normally round in shape and made from cotton fiber and used to filter components. The functional principle of the filter paper is separating the substances through them. They are normally made from fiber, which is the reason that there are keyholes on them. The keyholes resist the big solid particles and provide pathways for the liquid particles. And the most common usage for a filter paper nowadays is as a Printing Filter Paper.
