Filter Paper Grade 43
This filter paper sits between grades 40 and 41 in terms of particle retention but has twice the flow rate of Grade 40. It’s very useful when you need a good balance between particle retention and speed. Applications include:
- Foodstuffs analysis.
- Soil analysis
- Particle collection for XRF analysis (air pollution monitoring)
- Inorganic analysis in construction, mining, and steel industries
