Top 10 Ge Whatman Filter Papers

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Precipitates Retained: Coarse/Gelatinous. Filtration Speed: Medium-Fast. Nominal Retention 98% Efficient At: 15 to 19µm. Weight: 82g/m².

This Reeve Angel qualitative filter paper, Grade 802, is manufactured primarily for routine, noncritical laboratory filtration applications. It contains wet-strength additives and should not be used for Kjeldahl Nitrogen determinations. These Reeve Angel papers provide consistent quality and performance. For general and organic chemistry, pharmaceuticals, pharmacology, emulsions, petroleum testing, soaps and detergents, sugar filtration. Diameter: 32cm. Thickness: 0.26mm. Surface: Crepe, Prepleated. Shape: Circle. Precipitates Retained: Coarse/Gelatinous. Filtration Speed: Fast. Nominal Retention 98% Efficient At: 20 to 25µm. Weight: 73g/m².

This Whatman 7.0cm, grade 6, cellulose filter paper is used in qualitative analytical techniques to determine and identify materials. It has excellent fine particle filtration (3µm) in the qualitative range. It is capable of retaining the fine precipitates encountered in chemical analysis. This filter paper is twice as fast as grade 5, with similar fine particle retention. It is often specified for boiler water analysis applications. It is an excellent clarifying filter for cloudy suspensions and for water and soil analysis. Retention: 3µm. Diameter: 7.0cm. 100/Pack. Whatman #: 1006-070.

This Whatman 11.0cm, grade 5, cellulose filter paper is used in qualitative analytical techniques to determine and identify materials. It has the maximum degree of fine particle filtration (2.5µm) in the qualitative range. It is capable of retaining the fine precipitates encountered in chemical analysis. This filter paper has a slow flow rate. This is an excellent clarifying filter for cloudy suspensions and for water and soil analysis. Retention: 2.5µm. Diameter: 11.0cm. 100/Pack. Whatman #: 1005-110.

This Reeve Angel qualitative filter paper, Grade 230, is manufactured primarily for routine, noncritical laboratory filtration applications. It contains wet-strength additives and should not be used for Kjeldahl Nitrogen determinations. These Reeve Angel papers provide consistent quality and performance. For fine chemicals, pharmacology, oils, culture media, emulsions, soaps and detergents, water tests. Diameter: 15cm. Thickness: 0.40mm. Surface: Crepe. Shape: Circle. Precipitates Retained: Coarse/Gelatinous. Filtration Speed: Very Fast. Nominal Retention 98% Efficient At: 25 to 30µm. Weight: 123g/m².

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters. Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). More absorbent than Grade 1. 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. Also available prepleated as Grade 2V.

Grade 8 Ruled Special-Purpose; White cotton linter paper w/5mm green rules are resistant to aqueous, non-aqueous solution; Porosity: Coarse; Diameter: 70mm; Flow Rate: Fast; Particle Retention: 20-30µm
