Features and Benefits
- A general purpose creped filter for less critical routine analysis.
- Widely used to assay sucrose in cane sugar and within pharmaceutical laboratories for routine filtration.
General description
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. Some wet strengthened grades are available in folded (prepleated) forms.
