Whatman Grade 2 Qualitative Filter Papers - 1002-150


Whatman Grade 2 Qualitative Filter Papers are used in qualitative analytical techniques to determine and identify materials. Also available pre-pleated as Grade 2V, which give improved flow rate and increased loading capacity compared to equivalent flat filters.
More absorbent and slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). 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.

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 ± 0.5 g, SD < 0.3 g) and dried (24.7 ±0.5 g, SD <0.3 g) weight requirements.
