Grade 2 Qualitative Filter Paper Standard Grade, circle, 110 mm. These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Slightly more retentive than WTF-1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). More absorbent than WTF-1. In addition to general filtration in the 8 µm particle size range, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials. Also used for monitoring specific contaminants in the atmosphere and in soil testing.
