Filter Paper, round, Grade 2, 55 mm, 100 pc/PAK

Whatman Grade 2 is equivalent to filter papers Schleicher &Schuell 597 and Munktell no. 2.
Characteristcs:

• medium retention and flow rate
• filtration time of 240s/100 ml

A standard grade filter used for monitoring specific contaminants in the atmosphere and in soil testing. 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. Grade 2: 8 µm
