WHATMAN: Grade 2 Qualitative Filter Paper

Grade 2 is slightly more retentive than Grade 1, with an equivalent increase in filtration time.

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.

Grade 2: 8 um (medium flow filter paper)

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 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.

Properties

  • – Particle retention: 8µm
  • – Nominal thickness: 190 µm
  • – Nominal basis weight: 97 g/m2
  • – Nominal ash content: 0.06%

Applications

  • – Plant growth trials, where the extra absorbency is utilized to hold soil nutrient
  • – Contaminant monitoring in air and soil
