Grade 2542 is a high-purity hardened ashless quantitative filter paper designed for laboratory and analytical filtration applications requiring very slow filtration, excellent retention and high chemical resistance.
The filter paper features a very hard and strong surface, providing excellent mechanical stability during filtration and handling. Its hardened ashless construction ensures extremely low ash content, making it suitable for analytical procedures where filter purity and accurate gravimetric results are important.
Grade 2542 is particularly suitable for gravimetric metal determinations and other critical analytical filtration processes. Its very slow filtration speed allows effective retention of fine particles and precipitates while maintaining the integrity of the filter paper.
