General description

The maximum ash content of these filter paper grades is intermediate between ashless and qualitative grades. They are particularly suitable for Büchner filtrations where it is desirable to recover the precipitate from the filter surface after filtration. Other characteristics include high wet strength and chemical resistance which are similar to the acid hardened ashless filter papers.

Grade 52: 7 μm (medium filter paper)

The general purpose hardened filter paper with medium retention and flow rate. Very hard surface.
