Grade 113 Qualitative Filter Paper Wet-Strengthened, 125mm Circle, 100/Pk SKU: 1113-125

Qualitative Filter Paper - 1113-125

Routine laboratory filtration demands a filter paper that delivers consistent particle retention without slowing sample throughput. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Non-hardened cellulose delivers the flow rates and retention that routine methods require at practical cost per determination.
• Enhanced mechanical properties support high differential pressures typical of vacuum manifold applications in high-volume laboratories.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Whether your method requires simple clarification or precise gravimetric determination, the documented specifications above define what this paper delivers. To meet this need, standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
