Brand: Whatman

Whatman Grade 93 is a paper filter equivalent to Schleicher & Schuell 0859 and Munktell 3m/N Properties: Medium fast filter -filtration speed of 80 s/100 ml Grade 93 lies between Grades 1 and 4 in terms of filtration speed and retention. 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. 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-timMeer tonen
