Description
Description of Qualitative 2.5 Micron Filter Paper
Hawach is a decade-old filter paper manufacturer with a more competitive price, qualitative 2.5 micron filter paper is a star product equivalent to Whatman’s Grade 5 which has a high retention rate and slow flow rate. Because the filter paper is made of cellulose, its surface has numerous micropores for liquid particles to pass through, while larger solid particles cannot pass. This property allows the separation of liquid and solid substances that are mixed together.
Grade 5 filter papers used in paper chromatography are the same as 20 micron filter paper. These uniform, smooth, white sheets are the high purity, high quality, and high-value standard.
Features of Filter Papers Used in Paper Chromatography
1. Filter papers used in paper chromatography is micropores, small pore size, a large number of perforations
2. Filter paper manufacturers provide disc and sheet type, regular size or customized size and shape are all available
3. Qualitative 2.5 micron filter paper is suitable for samples with small Rf values and developers with low viscosity, but with longer deployment time
4. Pore size 2.5μm with high retention and slow flow rate
Advantages of Qualitative Grade 5 Paper
1. Full range of grade 5 paper diameter provide
2. Filter paper manufacturers provided the lowest ashless content: < 0.1%
3. Hawach filter paper have passed ISO9001 and CE third-party certification
4. Uniform distribution of micropores
5. High purity and consistent performance
Applications of Micron Filter Paper
1. Micron filter papers used in paper chromatography is excellent for clarifying filter for cloudy suspensions.
2. Hawach qualitative filter paper is used for 2.5 micron filter paper chemical analysis applications, corresponding filtration separation, and is frequently used for clarifying liquids.
3. Filter papers used in paper chromatography are an excellent clarifying filter for water.
