Filter Paper, Grade 1: 9µm
Grade 1: 9 μm,Grade 1 filter paper is 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.
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.FP-001 -

Filter Paper, Grade 2: 9µm
Grade 2: 9 μm,Grade 2 filter paper is slightly more retentive and having more absorbing power than Grade 1 with a corresponding increase in filtration time. In addition to general filtrations, 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.

Filter Paper, Grade 3: 5µm
Grade 3: 5 μm,Grade 3 filter paper is almost 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 Buchner funnels. The high absorbency is particularly valuable when the paper is used as a sample carrier.

Filter Paper, Grade 4: 22µm
GRADE 4: 22 μm,Grade 4 filter paper is a standard grade filter paper used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical. Grade 4 filter paper is extremely fast filter paper 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. These cellulose filters are used in qualitative analytical techniques to determine and identify materials.

Filter Paper, Grade 5: 2.5-3µm
GRADE 5: 2.5-3 μm,Grade 5 filter paper is a standard grade clarifying filter paper excellent for cloudy suspensions and for water and soil analysis. This grade of filter papers provides maximum degree of fine particle filtration in the qualitative range. Capable of retaining the fine precipitates encountered in chemical analysis. Slow flow rate.
