Qualitative filter papers, wet-strengthened
Filters Filter Papers Qualitative Filter Paper
These qualitative filter papers are essentially used for analytical purposes and routine analyses, whenever no gravimetric analyses are required. They are wet-strengthened and can be used for pressure and vacuum filtration. They are made of refined pulp and linters with an >95% alpha-cellulose content, are very pure with an ash content <0,1%.

Grade 1288: For coarse-flocculent and voluminous precipitates, especially iron, aluminium and chromium hydroxides; copper, bismuth, cobalt and iron sulfides; various organic, colored metal deposits; determination of silicon in analysis of steel and pig iron; for acidic and slightly alkaline solutions; pressure filtration.

Grade 1289: The most used grade for analyses; for relatively coarse precipitates such as silver, arsenic, antimony, cadmium, lead, iron and manganese sulfides; lead chromate; ammonium phosphorous molybdate; alkaline earth carbonates, ...; for acidic and slightly alkaline solutions; pressure filtration.

Grade 1292: Rapid filtration of fine precipitates; magnesium ammonium phosphate; magnesium ammonium arsenate; relatively coarse forms of barium sulfate; for acidic and slightly alkaline solutions; pressure filtration.

Grade 1290: For filtration of fine precipitates; barium sulfate; lead molybdate; lead dioxide; calcium hydroxide; calcium fluoride; nickel, zinc and stannic sulfides; for acidic and slightly alkaline solutions; pressure filtration.

Grade 1291: Ideal for particularly difficult filtration conditions and especially fine-grained precipitates; cold-precipitated barium sulfate; meta-stannic acid; copper oxide, ...; for acidic and slightly alkaline solutions; pressure filtration.
Grade 293: Ideal for particularly difficult filtration conditions and especially fine-grained precipitates; barium sulfate; copper oxide; common, often specified grade for clarification of wine.
