How To Select The Right Filter Paper

Hawach Scientific co., LTD. is the production of filter paper professional manufacturers. Professional production of qualitative filter paper, PH test paper, quantitative filter paper. Hawach has advanced production technology and perfect testing equipment.

Filter paper is a kind of paper with good filtration performance, loose paper, strong absorption of liquid. It is ideal for separating small substances in liquid or air. It is used in scientific laboratories to remove solids from liquids. Filter paper is commonly used in analytical laboratories as a filter medium to separate the solution from the solid.

There are three types of filter paper: quantitative analysis filter paper, qualitative analysis filter paper, and tomographic qualitative analysis filter paper. Quantitative filter paper and qualitative filter paper these two concepts are cellulose filter paper, not applicable to other types of filter paper such as glass microfiber filter paper. Qualitative filter paper performs well in qualitative chemical analysis and corresponding filtration separation.

Qualitative filter paper is generally used to filter the solution, to do chloride, sulfate and other qualitative tests without the need to calculate the value; Quantitative filter paper is used for precise calculation of the value of the filtration, such as determination of residue, insoluble matter, etc., general quantitative filter paper filtration, but also need to enter the high-temperature furnace for processing.

How to select the right filter paper?

The filter paper selection should mainly consider the following three points:
1. Effective area, namely filter paper use area is big, dust capacity is big, resistance is small, service life is long, of course, the cost also increases accordingly.
2. The smaller the fiber diameter, the better the interception effect and the higher the filtration efficiency.
3. The content of the binder in the filter material content of binder, the high tensile strength of the paper, high filtration efficiency, less hair phenomenon, filter material background dust small, good resistance, but the corresponding increase in resistance.
