Grade 598 1/2 Qualitative Filter Paper Folded (Prepleated), 125mm, 50/Pk SKU: 10312244

Qualitative Filter Paper - 10312244

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Taken together, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Rated at 8-10um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Non-strengthened paper is appropriate for routine gravity filtration where prolonged vacuum exposure is not part of the workflow.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. For this application, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
