High purity qualitative filter paper
Filtros Papéis de Filtro Papel de filtro qualitativo
These qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers cover a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions.

Grade 5 and V5: Very fast filtering, open fiber matrix. For coarse and voluminous precipitates such as iron- aluminum- and chromium hydroxide; Si- determination in steel and pig iron analysis.
Grade 3: Fast filtering, open fiber matrix. For coarse and voluminous precipitates such as iron- aluminum- and chromium hydroxide; Si- determination in steel and pig iron analysis.

Grade V150: Medium fast filtering, open to medium fiber matrix. For qualitative tasks, coarser precipitates such as lead-, iron- and silver sulphide; alkali carbonates; calcium oxalate.
Grade 1F and V1F: Medium to slowly filtering, medium tight fiber matrix. For fast filtration of fine precipitates such as calcium oxalate, magnesium ammonium phosphate, coarser forms of barium sulphate.

Grade Munktell no. 1 and 292: Medium to slowly filtering, medium tight fiber matrix. For fast filtration of fine precipitates such as calcium oxalate, magnesium ammonium phosphate, coarser forms of barium sulphate.
Grade Munktell no. 2 and 292a: Slowly filtering, tight fiber matrix. For filtration of fine precipitates such as lead dioxide, calcium fluoride, nickel sulfide, zinc sulphide.

Grade 106: Slowly filtering for fine precipitates such as lead dioxide, calcium fluoride, nickel sulphide and zinc sulphide.
Grade 120H and V120H: Very slowly filtering, tight fiber matrix. For fine precipitates such as barium sulphate, metastannic acid and cuprous oxide.
