Grade 598 1/2 Qualitative Filter Paper Folded (Prepleated), 240mm, 50/Pk SKU: 10312251

Qualitative Filter Paper - 10312251

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Available in circles, sheets, and prefolded formats to match specific funnel geometries and sample processing workflows. Ultimately, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• At 8-10um rated retention, the fiber matrix captures particles above the threshold while allowing smaller materials to pass through.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Uniform fiber distribution across the sheet ensures consistent particle retention from edge to center for reproducible filtration results.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.

When your analytical procedure specifies a particular grade, the retention and purity characteristics documented above confirm method compliance. Standard qualitative construction integrates into your existing funnel hardware, requiring no new equipment investment for reliable results. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
