Grade 802 32CM 100/Pk 100/Pk SKU: 5802-320

Qualitative Filter Paper - 5802-320

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. In practice, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Manufactured to a basis weight of 73g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.

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. Sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• 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.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
