Grade 1 Qualitative Filter Paper, Standard, 270mm Circle, 100/Pk SKU: 1001-270

Qualitative Filter Paper - 1001-270

Separating precipitates from analytical solutions requires a cellulose matrix with the right balance of retention and flow rate. Controlled fiber density produces documented flow rate and retention characteristics that remain consistent across production lots. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Standard cellulose construction provides reliable performance for gravity filtration and light vacuum applications.
• Manufactured to a basis weight of 87g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Economical unit cost at the pack quantities routine laboratories consume keeps your filtration budget aligned with actual throughput demands. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• 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.
• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
