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