Qualitative Filter Paper - 10311649
From student teaching labs to production QC departments, qualitative filter paper remains the workhorse for routine particle separation. 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
- Standard construction provides the absorption and wicking characteristics that gravity-based filtration protocols require.
- Nominal retention of 4-7um provides the particle size cutoff appropriate for the analytical or preparative separation method.
- Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
- 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.
When your application makes the filter paper part of the measurement, the ash and weight specifications above define its analytical contribution. 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.
