Qualitative Filter Paper, Medium Fast, 11 um, 110mm, 100/Pk SKU: CF15033

Qualitative Filter Paper - CF15033

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Together, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• Ash content of ≤0.15% provides the documented blank value specification that quantitative analytical methods require.
• Flow rate above general-purpose levels reduces filtration time for routine methods that do not require fine particle discrimination.
• Rated at 11um particle retention, the fiber matrix provides a defined cutoff for consistent separation across analytical batches.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Basis weight of 80±5g/m² indicates the fiber mass per unit area that controls retention, flow rate, and mechanical strength.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Specifically, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

• Pigment Screening - Separates undispersed colorant particles from coating formulations during color development and QC testing.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Botanical Extraction - Separates plant tissue debris from aqueous and solvent extracts during natural product preparation workflows.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
