Whatman Grade 93 Qualitative Filter Paper Wet-Strengthened, 125 mm Circle
* 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.
* This Filter paper is intermediate in speed and retention between Grades 1 and 4. Available in a dispenser pack, which can be attached to the wall or bench, placed on a shelf either upright or flat, and used as a normal carton or as a convenient dispenser.
* The envelopes are released individually for easy one-at-a-time removal. Package and envelopes are clearly marked for size and content.
Packing : 100's/Box
