Grade 93 Qualitative Wet Strengthened Filter Paper - 10 µm, Medium Flow Rate - 100 Circles

Grade 93 filter paper is intermediate in speed and retention between Grades 1 and 4. 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. Some wet strengthened grades are available in folded (prepleated) forms.
