* Qualitative Filter Papers

Wet-Strengthened Grades

These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin. Normal qualitative applications will not introduce any significant impurities into the filtrate. The resins do, however, contain nitrogen so these grades should not be used in Kjeldahl estimations, etc. All wet-strengthened grades are available in folded (prepleated) forms (Grades 113V and 114V).

Grade 91: 10µm

A general-purpose crêped filter for less critical routine analysis. Widely used to assay sucrose in cane sugar and within pharmaceutical laboratories for routine filtration.

Grade 113: 30µm

Ultra high loading capacity with a particle retention making it ideal for use with coarse or gelatinous precipitates. Fastest flow rate of the qualitative grades. Creped surface. Thickest filter paper in the Whatman range.

Grade 114: 25µm

Only half the thickness of No.113 and suitable for coarse or gelatinous precipitates. Smooth surface for easy recovery of precipitates.
