Qualitative Filter Papers
The most widely used filter paper for routine applications with medium retention and flow rate. This grade covers a wide range of laboratory applications and is frequently used for clarifying liquids. Traditionally, the grade is used in
qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate.
- In agriculture, it is used for soil analysis and seed testing procedures.
- In the food industry, Grade 1 is used for numerous routine techniques to separate solid foodstuffs from
associated liquid, or extracting liquid and is widely used in education for teaching simple qualitative analytical
separations. - In air pollution monitoring, using circles or rolls, atmospheric dust is collected from airflow and the stain intensity
measured photometrically. - For gas detection, the paper is impregnated with a chromogenic reagent and color formation is quantified by
optical reflectance. Available fluted as Grade 1V.
Slightly more retentive and absorbent than Grade 1, with a corresponding increase in filtration time (i.e. slightly slower filtration speed). 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. Available fluted as Grade 2V.
Double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate
can be held without clogging.
- The extra thickness gives increased wet strength and makes this grade highly suitable for use in Büchner funnels.
- The high absorbency is particularly valuable when the paper is used as a sample carrier.
Extremely fast filtering with excellent retention of coarse particles and gelatinous precipitates such as ferric
hydroxide and aluminum hydroxide.
- Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis.
- Used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical. Available fluted as Grade 4V.
