Frequently Asked Questions

What are Whatman Grade 40 ashless filter papers used for?

Grade 40 filter papers are designed for quantitative analysis and gravimetric testing, where extremely low contamination is critical. They are commonly used in soil analysis, metal testing (cement, iron, steel), and sample preparation for spectroscopy.

What does “ashless” mean and why is it important?

“Ashless” means the filter contains very low ash content (≤0.007%), ensuring minimal residue after burning. This is essential for accurate weight measurements in analytical procedures, especially when analyzing trace elements.

What is the particle retention and filtration speed of Grade 40?

Grade 40 offers a medium filtration speed with approximately 8 µm particle retention, making it ideal for balancing filtration efficiency and speed in routine analytical workflows.

What material is used in Grade 40 filter paper and how does it affect performance?

These filters are made from high-purity cotton linters (cellulose), which provide consistent porosity, high strength, and low contamination levels. This ensures reliable, reproducible results in sensitive laboratory analyses.
