Grade 2 Qualitative Filter Paper, Standard, 90mm Circle, 100/Pk SKU: 1002-090

Qualitative Filter Paper - 1002-090

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. Together, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• 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.
• Rated at 8um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. For this purpose, economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• 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.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
