Product Name: Quantitative Filter Paper
Brand: Jiaojie
Material: Cotton Fiber Filter Paper
Filter Speeds: Fast, Medium, Slow
Filter paper is made of cotton fibers and is manufactured using different methods depending on its purpose. Because it is made of fiber, its surface has countless small pores that allow liquid particles to pass through, while larger solid particles cannot pass through. This property allows the separation of mixed liquid and solid substances.
Regarding the difference between qualitative and quantitative filter paper:
Quantitative filter paper is primarily used for analytical experiments requiring ashing and weighing after filtration, such as gravimetric analysis in quantitative chemical analysis and related analytical tests. The ash content per sheet of filter paper after ashing is a fixed value.
Qualitative filter paper is used for general filtration, such as qualitative chemical analysis and related filtration separations. The main difference between quantitative and qualitative filter paper lies in the amount of ash produced after ashing: qualitative filter paper should not exceed 0.13%, while quantitative filter paper should not exceed or equal to 0.0009%.
