Grade 602 h 1/2 Qualitative Filter Paper Folded (Prepleated), 240mm, 100/Pk SKU: 10312651

Qualitative Filter Paper - 10312651

Laboratories processing dozens of samples daily need a qualitative filter paper that performs reliably from the first sheet to the last. Pure cotton linter cellulose provides a uniform fiber matrix with consistent porosity and predictable retention across standard grade designations. Each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.

Key Filter Paper Characteristics

• At 84g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Untreated cellulose provides the natural wicking and absorption properties that gravity filtration methods utilize.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• At <2um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.

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. Under these conditions, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. 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.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
