Grade 5 Qualitative Filter Paper, Standard, 240mm Circle, 100/Pk SKU: 1005-240

Qualitative Filter Paper - 1005-240

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. Taken together, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Standard cellulose construction eliminates chemical treatment steps that could introduce background contamination in sensitive analytical methods.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. In particular, consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
