Cambridge Brand Qualitative Filter Paper Grade 5 Circles

Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications. These grades contain a high level of alpha-cellulose that provides high purity but will weaken when wet.

The inherent strength of standard (untreated) grades does not pose a problem when they are used in routine quadrant folded applications. We do not recommend these grades for use in vacuum work or when wet handling is required.

This grade is a slow flowing filter designed to retain fine particles encountered in qualitative analysis. Grade 5 is widely used for water analysis, biological products and fine precipitates such as cold precipitated barium sulfate. Grade 5 is also used in Buchner funnels and to clarify cloudy suspensions.
