Sartorius Quantitative Filter Papers
C7-56
These filter papers are used for quantitative analysis. They are made of refined pulp and linters with over 98% alpha-cellulose content. Moreover, these filter papers are guaranteed to be
free of any residual acids that are used in a few production methods. Another advantage is their extremely low percentage of ash content. As a result, these filters are virtually ash-free.
Sartorius Ashless Filter Papers, with the grade Numbers 388, 389, 390, 391, 392 and 393, are characterized by high wet strength and high purity, classified according to their separating
capacity. These papers are especially suitable for quantitative analysis, Buchner funnels, pressure or vacuum filtration and are available in different formats as in reels, sheets, discs, and
folded filters.
