Catalog Number - CS10-CFP1-047

The CS10-CFP1-047 Antarisz Filter Paper is a high‑quality qualitative cellulose filter designed for gravimetric analysis and general laboratory filtration.

Manufactured from refined pulp and alpha linters, this filter paper is acid washed to ensure very low ash content, making it suitable for analytical applications requiring minimal residue after filtration. Its medium flow rate and ~11 µm porosity provide a balanced combination of filtration speed and retention efficiency.
