Filter Paper, Quantitative, Hardened Low Ash, Grade 54, Cytiva Whatman™
The maximum ash content of this grade is intermediate between ashless and qualitative grades. They are particularly suitable for Buchner 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 54 - 20-25µm particle retention. 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.
