MN 615 ff: This paper is particularly suited for the analysis of fats. A special treatment with organic solvents guarantees that
these filters are practically free of fats and resins (ethersoluble residue<0.1mg for a 27 cm filter circle).
MN 715: This paper is also suited for the analysis of fats. Careful selection of the raw materials ensures a low ethersoluble
residue for these filters.

These papers are made hydrophobic (impermeable to water) by impregnation with a silicone. With the
aid of these filters, water can be separated from water-immiscible organic solvents in an elegant manner,
bymeans of a simple filtration.
