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. Grade 93: This filter paper is intermediate in speed and retention between Grades 1 and 4.

Whatman 1PS phase separator filter paper is impregnated with a stabilized silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through. After being shaken, the mixed phases are simply poured directly into the phase separatory filter which is quadrant-folded in a funnel. The separation is extremely rapid so it is unnecessary to wait until the two phases have settled into separate layers. Droplets are automatically separated after only a few moments,
