Property of Qualitative Filter Paper
Qualitative filter paper provided by Hawach Scientific generally can be used for general qualitative analysis and for filtration precipitation or suspension in solution, but cannot be used for quality analysis. However, compared with traditional qualitative filters, it gives an improved flow rate, high wet strength, and increased loading capacity. Such as Qualitative Filter Paper Disc Grade: BIO-1, Qualitative Laboratory Filtration Filter Paper Grade: BIO-2, Qualitative 20 Micron Filter Paper Grade: BIO-4, Qualitative Chromatography Filter Paper Grade: BIO-5.
There are three factors needing to consider in filter paper selection:
1. Effective area: the larger the effective area, the larger the dust holding capacity, the smaller the resistance, and the longer the service life. And of course, the cost is correspondingly increased.
2. Fiber diameter: The finer the fiber diameter, the better the interception effect and the higher the filtration efficiency.
3. The content of the binder in the filter material: The high content of the binder means the high tensile strength of the paper and high filtration efficiency. The phenomenon of hair loss rarely appears, with small dust, but the resistance increases accordingly.
