Grade 598 1/2 Qualitative Filter Paper Folded (Prepleated), 500mm, 50/Pk SKU: 10312256

Qualitative Filter Paper - 10312256

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. In effect, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• At 8-10um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.

When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. Addressing this directly, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• 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.
• 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.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
