Grade 595 1/2 Qualitative Filter Paper Folded (Prepleated), 150mm, 100/Pk SKU: 10311645

Qualitative Filter Paper - 10311645

Isolating precipitates from reaction mixtures requires a cellulose matrix that captures solid material completely without premature filter blinding. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. As a result, lot-level verification of retention, thickness, and ash content ensures predictable performance when scaling from method development to routine analysis.

Key Filter Paper Characteristics

• Standard wet strength is sufficient for conventional Buchner funnel and gravity filtration setups at moderate sample volumes.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• At 4-7um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.

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.
