Grade 595 1/2 Qualitative Filter Paper Folded (Prepleated), 90mm, 100/Pk SKU: 10311642

Qualitative Filter Paper - 10311642

From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. In effect, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
• Nominal basis weight of 68g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Standard cellulose chemistry eliminates the need for specialized disposal procedures your general laboratory filtration generates. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• 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.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
