Description

Description of Medium Flow Filter Paper Grade 40

Hawach BIO-40 Quantitative filter paper is a star product equivalent to Whatman’s filter paper Grade 40. Because Hawach integrates R&D and sales, our vacuum filter paper has more competitive. Filter paper filtration is more effective against chemical reactions, so it produces fewer impurities and can be used for quantitative analysis.

Quantitative medium flow filter paper Grade 40 has slow particle retention (8μm), but chemical filter paper bio-43 is the higher particle retention of 3um. Quantitative filter paper filtration is used in several test methods. Commonly used filters in many standardized test methods, such as sample preparations and gravimetric analysis.

Features of Quantitative Filter Paper Filtration

1. BIO-40 is equivalent to Whatman filter paper Grade 40
2. High-purity filters contain 0.007% maximum ash content
3. High retention rate
4. Medium flow filter paper
5. Filter paper filtration

Advantages of Competitive Vacuum Filter Paper

1. ISO9001 & CE third party certification
2. High purity and consistent performance
3. Lowest ashless content: < 0.007%
4. Full range of diameter and OEM size and types are available
5. Whatman Grade 40 equivalent quality but competitive vacuum filter paper
6. Easy to use: pre-cut filter paper for use directly

Applications of Quantitative Filter Paper Grade 40

1. Pressure filtration
2. Vacuum filtration
3. Particle size detection in dyes
4. Specific gravity analysis of cement, clay, iron and steel products
5. Separation of solids from aqueous extracts during routine analysis
6. Analysis of the specific gravity of milk sediment
7. Collect trace amounts of elements and radionuclides from the atmosphere
8. Clarification filtration of the solution before atomic spectroscopy
