Cytiva Whatman™ Grade 54 Quantitative Hardened Low Ash Filter Paper
Cytiva Whatman™ Grade 54 Quantitative Hardened Low Ash Filter Paper - 100 Circles
The maximum ash content of these 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.
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.
