LOW ASH FILTER PAPERS FOR QUALITATIVE ANALYSIS

DESCRIPTION | TECHNICAL ESPECIFICATIONS | APLICATIONS | ORDERING INFO | PDF

DESCRIPTION

Low ash filter paper (approx. 0.08 %) recommended for applications that require greater precision than routine laboratory work due to its low ash content

For specific analytical tests that require greater precision than ‘General use’ filter papers.
Made of super-refined cotton linters and cellulose.
α-cellulose content above 95 %.
Low ash content (approx. 0.08 %).
2 designs: plain (DP) and folded filters (DF).
The folded discs:
- Allow time and cost savings in the filtering process.
- Afford higher flow speed.
- Afford higher loading capacity.
