Properties of disc paper filters:
- These filters can be made with various raw materials such as quartz fibers, wooden fibers or carbon
- Size and thickness varies depending on the raw material used and the purpose for which the filters are needed
- These filters are selectively permeable to small sized particles
- They are ideal to be impregnated with different reagents to carry out pH, diabetes, urea, and pregnancy detection tests.
Technique used for filter paper discs: The technique used for filter paper discs is known as ‘depth filtration technique’. Parameters like adsorption, absorption, chemical properties of the liquid, particle size, mechanical retention, viscosity of the fluid, pH of the liquid, thickness of paper all affect the filtration capacity and permeability of disc paper filters.
