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.Grade 1573: 12-25 mum (fast, smooth filter paper)A fast filter paper with high wet strength.
