Description

Description of Medium Flow Filter Paper Grade 40

Hawach BIO-40 Quantitative filter paper is a star product equivalent to Whatman’s Grade 40. Because Hawach integrates R&D and sales, our filter paper price 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 bio-44 is the lowest 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 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 Filter Paper Price

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 equivalent quality but competitive filter paper price
6. Easy to use: pre-cut filter paper for use directly

Applications of Quantitative Filter Paper Grade 40

1. Pressure filtration
2. Vacuum filtration
