Filter description
These filters are suitable for quadrant folded or gravity flow applications. Contaning a high level of alpha-cellulose which provide high purity infortunatly weakens when wet. Their inherent strength is not a problem when used in routine quadrant folded applications. However, we don't recommend them for use in vacuum work or when wet handling is required.

Filter general application
Gravity Flow Filtration and sample preparation
-
Filter specific application
Filter papers Std-Grd 642 / 100C have finer particle retention compared to Himedia 601, however with slightly lower filtration speed. These filters have a higher absorption than Himedia 601. Used in agricultural and environmental laboratories for plant growth trials, soil testing, air analysis in monitoring specific contaminants and in the filtration of organic and sulfide precipitates.
