Grade 802 15cm 100/Pk 100/Pk SKU: 5802-150

Qualitative Filter Paper - 5802-150

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. With this in mind, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Basis weight of 73g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
• Strengthening treatment preserves paper structure through extended filtration runs where continuous wetting would weaken standard grades.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. With these demands in mind, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• 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.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
