Whatman Grade 2 Qualitative Filter Paper Standard Grade, circle

Whatman Grade 2 Qualitative Filter Paper Standard Grade, circle

This certified Grade 2 is tested according to the procedure detailed in ASTM E 2187-09, Sections 9.3.1 and 9.3.2. The paper meets both the conditioned (26.1 ±0.5g, SD ﹤0.3g) and dried (24.7 ±0.5g, SD ﹤0.3g) weight requirements. These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters. Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). More absorbent than Grade 1. In addition to general filtration in the 8µm particle size range, the extra absorbency is utilised, for example, to hold soil nutrient in plant growth trials. Also used for monitoring specific contaminants in the atmosphere and in soil testing.
