Filtres Fioroni - filtres sans cendre

Our ashless filter paper grades are made with 100% cotton linters .
As quantitative analysis requires a high purity, these papers are being washed out with acid and finally cleaned with demineralized water.
The ash content is less than 0,008 %.

Grade 11 Fast filtering

Wide pores filter paper used for coarse and voluminous precipitates such as iron- aluminium- and chromium hydroxide, Si- determination in steel and pig iron analysis.
