Description of 8 Micron Grade BIO 40 Medium Filter Paper
Filter paper grade bio-40 for conventional filtration. Filter paper in the laboratory is used to analyze the proportion of cement, soil, and metal components. As the main filter paper used to separate solid substances from the water phase extract in soil analysis, in quantitative milk composition analysis, filtration paper is used as a pure analytical grade clean filter before the yard absorption spectrum. It is also used for the high-purity collection of residual elements and radionuclides in the atmosphere.
Hawach Grade BIO-40 high-purity quantitative filter papers are used for quantitative and gravimetric analyses as well as for pressure or vacuum filtration. 8 μm conventional filter paper with medium flow rate and particle retention for specific gravity analysis, solution filtration, and air pollution. High-quality cellulose chromatography filter paper also provides OEM Service, small order acceptable.
Advantage of Filter Paper in the Laboratory
High purity and good performance ensure the correct result of testing
Full range of diameter and OEM size and types accepted
Whatman equivalent quality and specification but competitive price
It is very convenient for you to use for the pre-cut filter paper
8 micron medium flow filter paper
Features of Grade BIO-40 High-Purity Quantitative Filter Papers
1. Grade BIO-40 high-purity quantitative filter papers are very pure and suitable for various critical analysis filters.
2. Grey filter paper, medium velocity, and particle retention for conventional filtration

Applications of Filtration Paper
Filtration paper is used for specific gravity analysis of cement, soil, and metal.
As the main filter paper used in soil analysis to separate solid matter from water phase extract, In quantitative milk composition analysis, as the pure analysis level before the atomic absorption spectrum.
Filter paper in the laboratory is also used for high purity collection of residual elements and radionuclides in the atmosphere, or as impregnated filter paper to collect acidic and alkaline gases in the atmosphere, total arsenic content in food and feed, nitrates in forage grass, oxalic acid in vegetable cans, and boron content in fertilizer.
