Grade 114 Qualitative Filter Paper Wet-Strengthened, 185mm Circle, 100/Pk SKU: 1114-185

Qualitative Filter Paper - 1114-185

Sample clarification before instrumental analysis starts with a filter paper that captures interfering particles without introducing extractable contamination. Manufactured without chemical hardening or acid washing, qualitative cellulose delivers the unmodified surface properties routine filtration requires. In sum, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Standard construction provides the soft, conformable surface that seats properly in gravity filtration funnels without edge leakage.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
• Compatible with standard glass and plastic filter funnels, qualitative paper integrates into existing gravity filtration setups without modification.
• Nominal retention of 25um provides the particle size cutoff appropriate for the analytical or preparative separation method.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.

When your multi-site study requires comparable data across laboratories, papers manufactured to tight documented specifications ensure your results align. Consistent sheet-to-sheet performance reduces the variability your operators encounter during high-volume daily filtration workflows. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
