Quantitative Ashless Filter Paper


Equistix filter papers are used for quantitative analysis and designed for preparation of samples and gravimetric analysis.
They are made of refined pulp and linters with virtually 100% of alpha-cellulose content.
Ashless filter papers for quantitative analyses are suitable for Buchner funnels and for filtration under pressure.
