Applications
Thick with a high loading capacity, Grade 6 provides similar particle retention to Grade 5 with twice the flow rate. It has high absorbency and increased wet strength, and is often specified for boiler water analysis.
- Plant growth trials, where the extra absorbency is utilized to hold soil nutrient
- Contaminant monitoring in air and soil
