• 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 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
