Grade 202 Cellulose Filter Paper, 32 cm Circle, 100/Pk SKU: 5202-320

Qualitative Filter Paper - 5202-320

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. Quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Manufactured to a basis weight of 82g/m², each sheet delivers the documented mass consistency that gravimetric methods require.
• At 15-19um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Strengthening treatment preserves paper structure through extended filtration runs where continuous wetting would weaken standard grades.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. For this purpose, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• 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.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Lysate Clarification - Separates cellular debris from crude lysates before downstream chromatographic or electrophoretic analysis.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
