Grade 520 bll 1/2 Filter Papers for Technical Use FF 385mm 50/Pk SKU: 10331554

Qualitative Filter Paper - 10331554

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Working in concert, from fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Untreated cellulose construction provides the pure, unmodified surface appropriate for routine filtration and general sample preparation.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. 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.

• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Botanical Extraction - Separates plant tissue debris from aqueous and solvent extracts during natural product preparation workflows.
