These filters are treated with a strong acid to remove trace metals and produce high wet strength and chemical resistance. They are particularly suitable for Buchner filtration where the tough, smooth surface of the filter facilitates the recovery of precipitates. The maximum ash content of these grades is between ashless and quality grades. They are particularly suitable for Buchner filtration where it is desirable to recover the precipitate from the filter surface after filtration. Other characteristics include high wet strength and chemical resistance similar to those of acid-curing ashless filter papers. Very fast filtration for use with coarse and gelatinous precipitates. High wet strength makes this grade very suitable for vacuum-assisted fast filtration of ''difficult'' coarse or gelatinous precipitates. Hardened low ash: 0.015% ash maximum Grade 54: 22 μm Properties: Very fast filtration, filtration speed of 39 s/100 ml The certificate can be found here: <aNäytä lisää
