Ahlstrom offers a complete range of low ash filter papers for general laboratory work that provides you with the correct combination of particle retention, filtration speed, loading capacity and wet-strength. Qualitative analysis, low ash content 0.06 percent, untreated, consistent performance, wet-strengthened grades, custom cut. 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 617 is also found in construction product testing and is used by students to retain large flocculents and precipitates.

Way too thick and doesn't let liquid through enough, so your filter will take forever. Stick to the VWR stuff. At least the price was competitive.
