Filtry jakościowe Grade 2

Filtr standardowy stosowany do monitorowania określonych zanieczyszczeń w atmosferze i w badaniach gleby.
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.

Grade 2: 8 µm
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.

Product 1002-500: Discontinued. No new products will be manufactured after 30th September 2017. No alternative is available.
