This Whatman 15.0cm, grade 114 filter paper is extremely strong. It has 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 this grade should not be used in Kjeldahl estimations, etc. This filter paper is only half the thickness of Grade 113, and is suitable for coarse or gelatinous precipitates. The smooth surface allows

This Whatman 5.5cm, grade 2, cellulose filter paper is used in qualitative analytical techniques to determine and identify materials. It is slightly more retentive (8µm) than Whatman Grade 1, with a corresponding increase in filtration time (i.e., slightly slower filtration speed). It is also more absorbent than Grade 1. In addition to general filtration in the 8 µm particle size range, the extra absorbency is utilized. For example, it holds soil nutrient in plant growth trials. Additionally,
