Which Kind of Filter Paper Is Suitable for You?
Filter paper is frequently used in lab experiments. Filter paper loose and has a strong absorption ability to liquid. The filter paper commonly seen in the analytical laboratory is used as a filter medium to separate the solution from the solid.
The right filter paper will get twofold results with half the effort. Choosing the right filter paper can be determined by considering the following four factors. At present, the filter papers mainly include quantitative analysis filter paper, qualitative analysis filter paper and chromatographic qualitative analysis filter paper.
Hawach Scientific co., LTD. is specializing in the production of Qualitative filter paper, product quality stability, exported to all parts of the world.
Qualitative filter paper refers to “qualitative analysis filter paper”, which is compared with quantitative analysis filter paper and chromatography qualitative analysis filter paper. The paper is loose and has a strong absorption of liquid.
Qualitative analysis filter paper generally has a large amount of residual ash, which is only used for general qualitative analysis and filtration of precipitation or suspended substances in solution, not for quality analysis.
(1) the general use of natural filtration, the use of filter paper and the ability to trap solid particles, so that the liquid and solid separation;
(2) as a result of the filter paper mechanical strength and toughness are weak, as far as possible with less filtering method, such as must accelerate the filtering speed, in order to prevent filtering failure, in the air pump filtering, according to the size of the suction in the funnel stack 2 ~ 3 layers of filter paper, in the vacuum filtering, in the leakage.First pad a layer of dense press cloth, and then put filter paper to filter;
(3) filter paper had better not filter hot concentrated sulfuric acid or nitric acid solution.
