Grade 6 Qualitative Filter Paper, Standard, 185mm Circle, 100/Pk SKU: 1006-185

Qualitative Filter Paper - 1006-185

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Cellulose fiber matrix maintains structural integrity through standard gravity and light vacuum filtration conditions. To this end, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Pure cellulose without strengthening additives ensures the lowest possible extractable background for sensitive analytical methods.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.

If your laboratory runs standardized filtration protocols, the lot-level consistency of this filter paper protects your method reproducibility. Here, consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
