This Whatman 18.5cm, grade 91, general-purpose, crêped filter paper is intended for less critical routine analysis. It is widely used to assay sucrose in sugar and within pharmaceutical laboratories for routine filtration. Extremely strong filter paper, it has a high wet strength due to the addition of a small quantity of chemically stable resin. The resins do, however, contain nitrogen, so this grade should not be used in Kjeldahl estimations, etc. Normal qualitative applications will not introduce any significant impurities into the filtrate. Retention: 10µm. Diameter: 18.5cm. 1,000/Pack. Whatman #: 1091-185.
