Grade 2 Qualitative Filter Paper, Standard, 270mm Circle, 100/Pk SKU: 1002-270

Qualitative Filter Paper - 1002-270

Gravity filtration setups require paper that wets uniformly, seats flat in funnels, and retains particles at the rated threshold. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. In effect, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Manufactured to a basis weight of 97g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• 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.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. To address this, 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.

• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
