These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin.
| Code | Whatmans Grade 113 |
- 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 (pre-pleated) forms.
