Whatman™ Grade 2 Qualitative Filter Papers
Supplier: Cytiva
Certificates
About this item
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.
- Each lot is guaranteed to meet the ASTM E 2187-09 specifications
- Simplifies testing process by removing lot suitability testing
- Just condition and use
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. Also available prepleated as Grade 2V.
Certifications: 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. Tested according to the procedure detailed in ASTM E 2187-09, Sections 9.3.1 and 9.3.2.
