Ahlstrom Grade 617 Qualitative Filter Paper - 50 Circles 

Ahlstrom 617 is an extremely fast filtering grade and has a larger particle retention than Grade 631. Grade 617, a thicker filter paper with higher loading capacity, is used for rapid filtration of coarse particles and gelatinous precipitates such as in oils and resin solutions. Grade 617 is also found in construction product testing and is used by students to retain large flocculants and precipitates.


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.


Ahlstrom’s qualitative grades of filter paper are, by definition, recommended for use in analytical methods, which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance.

Format: Paperback
It does not prepare for the real test. Using it is absolutely not enough to be approved with good grades. Too expensive for what it offers.
