Grade 597 1/2 Qualitative Filter Paper Folded (Prepleated), 70mm, 100/Pk SKU: 10311841

Qualitative Filter Paper - 10311841

Teaching laboratories introducing filtration techniques need a paper grade that produces reliable results while remaining cost-effective for student use. Smooth surface finish allows clear visual assessment of retained solids and supports clean separation of precipitates from filtrate. Documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• At 85g/m² nominal basis weight, the paper provides the mass uniformity needed for reproducible gravimetric determinations.
• Standard construction delivers adequate wet strength for conventional filtration while maintaining economical cost for routine applications.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Cotton linter cellulose provides the clean fiber background your general analytical methods need without the cost of specialty grades. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Paint and Coatings QC - Removes gels and undispersed pigment from coating samples prior to color measurement and viscosity testing.
• Gelatin Clarification - Removes debris from gelatin solutions used in pharmaceutical capsule manufacturing and quality testing.
• Enzyme Clarification - Removes particulates from enzyme solutions before activity assays in biochemistry and industrial testing.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
