Characteristics and Selecting Factors of Filter Paper
Usually, there are four major properties for customers to choose their suitable filter papers. The chart has been summarized below.
|Hardness||The filter paper can become wet in the filtering procession, so some experimental steps with a long time should consider the tougher filter paper after its wetness.|
|Filtration efficiency||The density and size of the pore on the filter paper all impact the filtration efficiency that shows in fast filtering speed and high resolving ability.|
|Capacity||Solid particles can be accumulated during filtration and block small holes on the paper, so the denser the pore is, the higher the capacity would be.|
|Applicability||Some filter papers are manufactured according to especially given steps, such as the use of nitrogen-free filter paper in the determination of blood nitrogen content of pharmaceutical products.|
