Grade 604 1/2 Qualitative Filter Papers for Coarse Precipitates FF 125mm 100/Pk SKU: 10312744

Qualitative Filter Paper - 10312744

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. As designed, rigorous quality control at every production stage ensures physical properties align with published grade specifications before distribution.

Key Filter Paper Characteristics

• 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.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Non-strengthened grades deliver consistent retention at the economical price point that high-volume routine methods demand.

Reporting filtration parameters alongside your analytical results demands documented grade, retention, and lot traceability for reviewer confidence. 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.

• 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.
• Botanical Extraction - Separates plant tissue debris from aqueous and solvent extracts during natural product preparation workflows.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity 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.
