About Whatman Filter Paper

A filter paper is a semi-permeable paper used to separate fine solid particles from liquids or gases. It is made from fibrous material, such as cotton fiber, with tiny pores that allow the liquid or gas (the filtrate) to pass through while retaining the solid particles (the residue). This separation process is used in laboratories for analytical purposes and in everyday applications like brewing coffee

We have various brands like WHATMAN , SARTORIOUS , BOROSIL & MANY MORE.
